Epic Trial error after winning a game

Platform, device version and operating system: switch, v 9.2.0.00

What you were expecting to happen, and what actually happened:
I expected to see the rewards after winning a game in the Epic Trial and get the Starry pet. I have lost several due to the error. Last week, the same error occurred when I wanted to check the troops before the battle, now it looks ok.

What happened: Instead of the reward I got the error above and got nothing.

How often does this happen? When did it begin happening?
Every single time I play the Epic Trial game - have tried twice this week, both got the error above.

Steps to make it happen again
Go to Epic trial, win the battle

Sorry if this has been reported already. I did check other reported bugs but haven’t found one related to switch and epic trials

Thanks for reporting it. I double checked this on Steam/PC and it seems to be working fine on this platform. Might be a Switch specific bug?
