I’ll create a minimal example project if it would help (?) or maybe I could provide my project which is affected by this.

@olejnjak To give a progress update, we’ve been able to identify the issue. It’s triggered by configuring FirestoreSettings to use a concurrent queue, so for a quick workaround, you could change that to use a serial queue (which is the default). I’ll continue working on fixing this and will post an update when I have it.

Based on our current line of investigation, yes that seems to be the case, but we haven’t yet confirmed one way or the other.

By the problem I mean the “FIRESTORE INTERNAL ASSERTION FAILED: enterCheckedOperation may not be called when an operation is in progress” exception 😃
