@Suty Thanks. I have checked and compared it today that was raining, and it seems that it is working alright again. The radar matches the actual rain and website radar, so it seems that the issue is solved

Hi! I have seen this issue since several weeks ago. Radar and Radar+ plus show that there is no rain and it is raining. The rain maps of Radar and Radar+ are not correct. MeteoCat Radar, that it is from the Catalan goverment, shows a better and correct radar rain map at https://m.meteo.cat/temps-actual.
I'm at Barcelona city where it is now raining and I can sent screenshot of windy and MeteoCat Radar, so you can see the difference.
Best regards,
