Bug preventing pawn promotion

Hi, Im not sure if this is the right place to post this but I'm currently running into a bug that prevents me from promoting a pawn to another piece. The promote screen comes up, but clicking on any of the options doesn't do anything and after a couple of clicks the screen closes again. Same issue on the analysis board.

Browser: Waterfox 56.2.10.1 (64-bit)

No issues yesterday, no new browser updates since May 17th.

Had to swap to Chrome in the middle of a game. Promoting worked fine on Chrome.

Afterwards tried restarting Waterfox, clearing cache, complete pc restart. Nothing worked.

I don't think chess.com offers Waterfox support.

I've the same problem, in my last 2 games occurred this bug and I use Chrome on my android 9 smartphone, one week ago there wasn't this bug

Please send a bug report to support@chess.com  and include your device info (Android 9, Chrome version, etc.)

Today 26th of June vs solko100 I have 2 different pawn to promote and any kind of promotion work queen, knight... Simply the doesn't move

To open a bug report, is there any standard? Or can I send a simple email?

Are you guys in a club, chess.com beta?

When I was in beta, there were lots of bugs, which was part of the beta testing...
