I'm also having issues with the Custom colour scales. Sometimes the map data shows the right colours, sometimes it shows the default. Sometimes the map data shows the right colours. On several weather layers, the legend shows the default colours. Sometimes, when opeing the page for the first time, the map data is blank and I have to select other layers to get the map colours to start showing. The rain radar is one exception that seems to be OK with both map data and the legend. The iOS app has very similar issues.

@ivo Thanks Ivo. Deleting browsing data improved things. However, when I click Customize color scale from the setting menu, I still get an invisible menu for adjusting colour. In the attached image, there should be a menu on the left, but all I see is a cross to close the menu. The small temperature icon that cycles through nearby locations also doesn't appear when clicking a place on map.

I also have this from error console:

Hello,

While I was adjusting the colour scale for wind, I removed all the other colour options and saved before adding my own. Before I was able to add my colour options in, most of the menu's stopped working. I can no longer change what weather I want displayed. I can't open the colour scales to reset to default, I can't see any locations on the map, opening one of my favourite locations doesn't work, and I only have access to ECMWF model. Trying a different browser didn't work. The bug also affected the iOS app, but reinstalling fixed the app, except I can't see the temperature cycling through nearby locations above webcam image when tapping a location.
