I want to do this with my brother in law as he lives close to the Etihad and I live 3 hours away but when I spoke to someone at the club about the 2 downloads rule and if he could have it on his phone, I was told no as it goes against safety and security. They need to know who is in the stadium, if something happens, they would be looking for me not my brother. If I was caught doing that I could have my season ticket taken away!I'd implore you not to cancel your season ticket. The club have performed plenty of U-turns recently following pushback from fans and it's quite possible they could do the same with the 10 game minimum in-person attendance.
If they don't back down, consider getting a cheap burner phone that supports NFC and downloading your season ticket on to it. Then when you can't attend and family/friends go in your place just hand them the phone to scan themselves in so no need to transfer the ticket to F&F. Of course, if you're moving out of the area then the logistics of getting the phone to them and back to you might be an issue.
What I got told anyway…
