Game drops out on Samsung A70 companion app

Hi all,

Firstly apologies if in wrong topic area - newbie here.

I have been running Zwift for about six months and have have a working setup in the garage with HP laptop connected to 32" TV running the main Zwift connecting to my Elite Directo via Ant+. That all works perfectly and no issues. I also run the companion app on my Samsung A70 but often find that the ‘game’ drops out especially during events and will not reconnect despit closing and restarting the app on the Samsung.
All devices are connected to the same internet Wifi and does nto appear to be dropping out as all other functions continue to work.
Any ideas please?

Kind Regards
