FlexMatch - can't use Cognito identity id as playerId in FlextMatch

Hey @REDACTEDUSER

We have just deployed the update that will allow the FlexMatch API to use the same format for Player Ids as the rest of GameLift. It should be available in all regions by early next week.

Please let me know if you need any more help!

The update has been deployed to all regions. Thanks again for using FlexMatch!

Hey @pablo666-

We took a look and have verified what you are seeing. We agree that our API should be consistent in the characters we allow for PlayerIds and will be updating StartMatchmaking (and our other FlexMatch API) as soon as possible. I'll update you here when we release the fix.
