Ok. Thank you!

Coincidentally, ( after swapping in some apple weather elements via the phone yesterday ) this morning, I tapped on the little lightning symbol, and found install watch face at the bottom of the list.

Did that, and the whole Windy watch face came back; with proper information.

There is certainly a bug somewhere.

I have been having the same Celsius only problem for at least a month in the center complication 5 days. Coinciding with getting a new watch.

The phone has Fahrenheit and mostly US settings, iCloud sync is on, settings on the watch are not changeable, ... but the display continues to show the default metric units for all weather aspects.

No amount of fussing with it has resolved the problem. iCloud. No iCloud. Trying to change settings. Removing the watch face. Adding the watch face. Tried to solve this again today. The Apple Watch actually crashes when trying assign a complication from the Windy ... section. I can only pick the default options, and the windy watch face is actually entirely inoperable, when it comes to Windy stuff.

Apple stuff or other third party complications work fine.

Ok. Thank you!

1. Type of Watch face?
   The Windy watch face that the windy app installs / allows to install as a full screen Apple watch interface

2. WatchOS?
   WatchOS 26

3. Windy Version?
   Windy 46.010002

Basically everything that is up to date and the very latest.

I was really hoping this would not be the case, but updated my devices and now the watch face is dead.

Going into the windy app, looking to reinstall, it says the watch face is not compatible with the operating system.

Tried to add a photo, but the forum is not allowing me to upload an image; it just types code.

Anyhow. The watch face is blank with square blocks.

And it is stuck once again ...

Have restarted the phone and the watch.

Ok, well this morning, with my watch one and phone in my pocket ...

It had updated the weather to Tuesday, looked fine.

Then it did the default (?) PRAHA -113 on WED once again.

I just don't know why it does these things, watch is on my wrist, phone is in my pocket, I'm actually at home with with 2.4 & 5 ghz wifi for at least a hundred yards around the house ...

Now as I typing this, it just switched back to the correct info.

Just strange and buggy, really, which is sad, because I love windy otherwise and as somebody who spends a lot of time outside for maintenance, gardening, DIY ... I really love my wrist based weather center with outlook for the next few days.

@SimonUrbanek

Thanks, Simon

I just went through the suggested steps of switching to another middle complication, shutting down the watch, restarting, unlocking and setting it back to Windy 4 day ... and at first it came up with the same 4 day data from 2 weeks ago ... and then ... it refreshed to this week.

Hopefully I'm back on track.

Fingers crossed :)

Thanks again.

@Suty No. The only thing my watch has in particular is Display off / sleep [ always on = OFF ] , so it preserves the battery, I don't need it to be on 100% of the time.

I have verified app settings and background app refresh is ON for Windy on the watch.

@Suty Yes, the windy app on the phone works normal, gets the data.
And when I click on anything on the watch, I get the new data
I can click the wind or radar icon, and it will have the same as the phone, pull live radar, etc
Just the center multi day complication remains stuck.

@Suty

I checked my phone for pending updates, there was no update waiting for Windy.

I rebooted my Apple Watch, unlocked it, opened up the weather info, radar image etc ... so it gets the current info from the phone OK.

But the center compilation on the watch is still stuck on Friday 4 day.

@Suty It is not updating.

After whatever however, it did start working again.

For the past 3 days, again it is not updating. We're Tuesday and it still is stuck on last Friday's screen.

iPhone 14 Pro Max and Apple Watch 9, both set to auto-update as needed, software wise, which I think is pretty common. Watch and phone go on the charger at night. Get picked up in the morning, and I pretty much have my phone on wifi most of the day and in my pocket. If not it is on wifi then 2 bars of 5G/LTE. Really nothing particular use wise.

But, something stops communicating somehow for whatever reason and does not retry.
