There were definitely some changes to the servers: First in relation with the 1.15.10 update - which screwed things up totally for 2 days, then according to a forum mod the situation was “synced” with the update. Result was better, but we still had the issue with 12 hours of weather loading in advance (and hence 12 hours missing).
The issues were reported, and things changed again - to the stuck weather we have now. So there’s definitely something going on with the server situation - but if it has to do with beta testing and if the situation will changei for the better on tuesday I have no idea - only hope.
