After updating my phone to Android 11, I can’t connect to my RB4011 running 7.1beta5 for more than 30 seconds before the RB crashes and reboots. I don’t get anything in the logs other than a regular reboot message. And, I can’t just downgrade to a lower ROS version because I need Wireguard.
Think support will be really interested in your supout file:

They don’t want supout files with beta versions, only v6 right now.
