For those of us using Graphene, the above GitHub link references back to this article ([Niantic's Pikmin Bloom 110.1 is partially softlocked on Graphene OS · Issue #4663 · GrapheneOS/os-issue-tracker · GitHub](https://github.com/GrapheneOS/os-issue-tracker/issues/4663)), stating that the issue may be the Play Integrity API checks. Graphene recommends that app developers use Android’s hardware attestation API instead of the Google Play version as a way to maintain security while still remaining compatible with more devices (see [Attestation compatibility guide | Articles | GrapheneOS](https://grapheneos.org/articles/attestation-compatibility-guide)). I don’t know if everyone having this problem is running GrapheneOS or if it is affecting all OS equally but this may be a good place to start.

Niantic PLEASE fix this ASAP because it’s been almost a month since I’ve been able to play and it is really frustrating.
