App App development outside China but target China market

I am using react native to build app target for all countries, especially China customer.

What are the services that work in China, especially service like crash reporting, analytic and push notification?

1. Firebase. This need Google Play Service to work, since most of the Chinese phone does not have it installed, and google is banned, so can I safely give it a pass?
2. Microsoft App center. Does it work? I think Push notification still rely on the FCM.
3. AWS Amplify. Push notification rely on FCM.
4. Jiguan. It is chinese company, so it should have no problem, but they are lacking of crash reporting and cannot receive push notification when app is close.

Do you have experience on App development outside China but target China market?
