Phonak remote losing control

I have Audeo Marvel ear buds and have used them for years with BT enabled/app on my iPhone. Works in car as well beautifully no issues.

I recently bought a TV Connector box in addition to a Phonak Remote so I can control the ear bud tv volume/revert to hearing aid channel to talk to wife. Fresh battery too.

Problem I’ve run into lately out of the blue is I lose the ability to control the volume/channel change on my Phonak remote. Sometimes it’s when I fire the TV/Connector up right out of the gate and sometimes it will simply stop working during regular TV watching where it had worked 5 minutes before.

Best I can do is shut phone, tv, tv connector and phonak remote down and restart everything and it works. Simply wondering if there is a setting I can work with that will keep me from having to do this infernal shut down/restart in the middle of watching tv.

Thanks for any leads or solutions.

The Phonak phone app, turns the remote off.
When out of range of the phone, the remote turns itself back on.
I set my phone on a lawn chair, when I walked about 100 feet away, the remote turned back on.
