If the bug is specific to my device then I’ll provide more details upon request.
Twice today I’ve been notified about the 24 pet rescue at the end of a battle.
It’s never happened prior to patch 5.3
First time was at the end of an adventure battle. I ended that play session.
Came back and played a Tower of Doom battle and got the pet rescue splash screen at the end of the battle again.
Had it happen again after the 5-8 Arena victory today. This time on my Chromebook, not on my Android phone.
Happened again during a new arena run. Maybe tied to using new teams? Still on the Chromebook under the same play session.
I’ve gotten it too. Switched from Arena to PVP. Screen popped up. Switched to Explore, screen popped up. Did a delve & came back to main map, screen popped up. All in a single login.
