I have recently replaced Google Services Framework with microG. Since then, I’m not receiving push notifications from Monzo.
Unfortunately I don’t have many push notifications subscriptions, but EasyJet definitely worked. Monzo shows up as registered for GCM, but nothing seems to be coming through.
I’ve talked to Help over the app, and in theory, the messages do get generated from Monzo’s side.
I’d be more than happy to provide debug logs in order to have Monzo work with microG, but I’m not certain what is needed from me.
