Unable to play with friends

[Trek-1320]

Tried to play a few games today. Both of us tried restarting the game but it just keeps saying to wait for them to be in the main menu. I was on a PC they were using the mobile version.

Unable to challenge a friend on mobile?
If you are unable to duel a friend from your friends list, you will need to wait until both players are on the same patch.

You can check your build version on your mobile device in the Settings > Options menu. On desktop, you can check it on your Battle.net Launch next to the Play button.
