Pioneer DEH-S6120SB previously paired phone won't auto connect

We bought a used Toyota Sienna AWD Limited. The OEM radio did not have bluetooth so we had a Pioneer DEH-S6120SB installed, connected to the OEM Bose premium speaker system This was last April. Everything was great until three weeks ago when our phones stopped auto connecting. Blue tooth still works, but you have to manually pair the phones anytime the car is turned off and restarted.

Phones are a Moto G6 and a Note 5. Both phones still auto connect to our other car (a newer Toyota Venza with an OEM bluetooth radio.)

I have tried deleting all phones from the Pioneer, and forgetting the Pioneer from both phones, and repairing. No change. Phones will manually connect and function, but will not auto-connect when the car is turned off and restarted.

Any ideas would be appreciated.
