Quick answer: Introduce a platform-agnostic account identity that platform logins attach to, and merge progress and entitlements so the player is one account everywhere.

Players expect their progress to follow them across platforms. A unified identity delivers that. Here is how.

How to fix it

1. Create a master identity

Use a platform-agnostic account that each platform login links to.

2. Attach platform logins

Let players sign in with any platform and attach it to their master account.

3. Merge progress and entitlements

Reconcile progress and purchases across linked platforms so the player is unified.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every backend error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
