Nope that is not it both running iOS 9.3.3Perhaps it's the iOS version that's different? Are they running the same?
Yes. No how do i do that?@max2 are all the settings identical for both apps? Have you tried clearing the apps' cache on iPad Air 2?
I don't think it is the cache.Yes. No how do i do that?
Yep they both use the same Wi-fi.I don't think it is the cache.
What I am thinking about is different network settings. Do they both use the same wi-fi?
Also I think it would be useful for us to get your DNS requests log. Maybe we'll find something suspicious there.
Not sure believe I tried that and it didn't work but can't remember sorry.So @vasily_bagirov could be right about app cache after all.
In this case reinstalling tapatalk should have helped as well.
