I hate this. Why do I have to relogin to every app on a new phone? Why are some apps missing after every migration? Why do some apps just randomly lose all config and settings and force you to set them up again?
I want Google/Apple to force app devs to make backup and restore seamless. Like, if I am halfway through typing this comment on HN and then lightning fries my phone, when I restore to a new phone I want the exact same chrome tabs open with the same half-written comment. I don't want to have to battle to re-pair my printer or watch. I don't want stupid cookie warnings on every website again. I don't want to have to retrain every single fingerprint. I don't want to yet again opt out of data collection. I don't want to re-accept the same T&C's for photo backup I already agreed to last year, and the year before, and 10 years before that.
Please... just make migration work the way it should have always worked.
