iOS Premium Widget not working

[lllusion]

Non-premium widgets show data.
Premium Widgets state 'Open the Windy'. From within the Windy app premium features work. I've tried logging out of the app and logging in again. No change to the premium widgets, other than two notifications that the Windy icon changed (at log out then in again).

What to do?

Opening the Windy app and logging in if prompted always corrects this for me. (Come to think of it, this hasn't happened to me in a long while.)

I suppose if I were in your shoes, I would remove the widget, power off the device and power on again, then install the widget again. But, perhaps, before doing that, cycle airplane mode on and off. If you connected to wifi, cycle that off and on.

Next step after the above would be remove the app, power cycle the device, then install Windy again and log in.
