I am also having Bluetooth / pairing issues......I have a 11 Pro Max. It will not connect to a brand new Honda Accord......
my Bose Bluetooth Speaker
HK Onyx Studio
Powerbeats
Bose headphones
Total PA Pro
T&V Kurbis BT
T&V Laut BT
Samsung Soundbar
Basically nothing!!!!!...........And this is my second 11 Pro Max ......I got one on Friday .......returned it today for a new one........My new 1 day old 11 Pro Max does the same thing.......but at least the first one did pair to my car for 5 mins and kept disconnecting......This one wont even pair. I had the I Phone X prior and Bluetooth connectivity was flawless!!!!
I have several Apple products ...including...4 different IPads .....even the new IPad Pro .........never had a problem connecting or pairing to anything Bluetooth....
I read it might be a software issue 13.1 was to fix the connection bugs.......I updated and still nothing........what in the world !!!! Is the problem.
My wife has a new I phone 11 and she is having the same issues plus ......she cannot connect her I Watch ......and she is about to pull her hair out........plus she keeps loosing all her workout info........so she is not a happy camper........
I love the phone the camera is great......I think have not had much time to play with it ..........Way too busy trying to connect!!!!
I hope and pray this gets corrected quickly ................this is taking us back to rotary phones and 8 track tapes......lol......
Apple please correct this issue.......
