I’ve been using RP as my main audio pleasure in my Tesla since I got it - and in the past,  when the phone connected to the car, RP would just start (if it was active on my phone),  or I could just select RP and all would be good. But not any more -  routinely, I cannot get RP to even start in the car - the app just hangs. Works fine at home or in the shop when the phone is on wifi, but normally (not always) it refuses to open and run it the car. 
I’m running an iPhone 14 pro, verizon 5g, and the only possible change I can imagine (besides regular ios and app updates)  is that I added Tailscale to all my devices recently. Is that an error? It seems that - maybe I’m imagining it - if the phone is on LTE, RP seems to work in the car, but if the phone says 5g, RP wont even start, and I get an error saying there needs to be a network connection?  So - I’m lost - I gotta have my RP in my car, but I can’t figure out how to get ti back to working reliably!  Help!
