Infotainment gone offline.... Again.

As the title says my car has stopped sending information to the Skoda server and hence to the app on my android phone, no new info on my Ipad either. The little globe on top of the radio is greyed out and info is dated 9/5/23. This happened last December and I was without info for almost 3 weeks. Stupidly I contacted Skoda support and they just made everything worse by sending me instructions for a different head unit and getting me to do things that resulted in me losing all the cars stored data, they hadn't a clue what they were doing tbh. The radio came back online by itself on christmas day without me doing anything. I don't fancy chasing my tail with Skoda again, would anyone here have any suggestions? The car is a March 2021 iV style model with the Columbus head unit. One thing I did notice was the system rebooted by itself around the time it stopped sending info, I didn't take much notice as it goes through phases of rebooting and eventually settles down. The subscription is active until July, guaranteed it will be working when renewal is due....
