Unusual AppUser Created

Hi Everyone,
I was monitoring the RC Dashboard and saw a user make a purchase. Everything appeared normal. Firebase UID was the app_user_id, and the firestore database user record was updated correctly.

After about 5 minutes, I saw the app_user_id had changed to "Anna441994!", and a document had been created in the database under that uid.

I have opened a support ticket for this, but wanted t see if anyone else had seen this and if this is a hack by some desperado.

I’m concerned it may be the latter.

I have attached screen grabs of the data i’m seeing.

Cheers

MichaelC
