I use MRLevel3 on my Win10 Phone. It has worked fine for years, but suddenly it quit loading radar data yesterday.
It was set to get the data from NWS, for some reason I don't recall.
I changed it to Allisonhouse and it started working again. It this yet another case of NWS moving servers around? I don't see any way to change the URL in the phone app.
At least it is going again using the Allisonhouse feed.
