Katana Air EX

Hello guitar fans!!!
I am thinking about buying a katana air EX for the convenience of playing outside or in a group class.
I read reviews of how great this amp is but others mentioned connectivity issues.
What should I believe???
I already had to deal with background noise with katana and not been able to use boss tone studio and upgrades (I use iPad or cell) .
So I just want plug and play (simple) would the katana air EX do that for me?
Feedbacks are welcome (and thank you for you, for taking the time to reply).

I’ve not got an EX but have the original katana air and never had any issues with it either wirelessly or via cable.
