I recently installed graphene on a new to me phone. I am attempting to use a product called SMS Backup and Restore to more some things over from my old phone, but cannot do so because it needs to be set as a default app and my phone denies that. Warning photo attached.

I poked around in Matrix but didn’t see any mention of this but am pretty unfamiliar with how to use Matrix.

Any graphene users have advice? It seems like it must be so simple and the graphene and other forums mention using this software. I have allowed all visible permissions for now, and all seeming relevant ones for the google support programs.
