I found a old ipad which i want to use with infuse 6 pro. Home on wifi it works fine, but when i am out or on flightmode, it tells me that my licens will exspire on january 27 and that i should connect to the internet to update. I have done this many times. I also have reinstalled the app.
When looking in my subscribtions in iCloud, my monthly renewed subscribtion is valid until february 12.
Can you try downloading today’s 6.2.7 update? Downloading updates can help update the details with the App Store, which can help resolve issues like this.
