Hello! First of all:
1. I've looked here already:

2. I've manually searched the Portable Devices sub-forum back to Jan 2020.
3. I did an automated search and found this:
https://getmusicbee.com/forum/index.php?topic=22995.0 (which didn't help).
Alas, I still can't get it to work.
Here's the deal: I just want to sync four playlists to the phone. At first I checked the Devices section of preference and found two list items for my phone. I selected the first one and tried to sync but it didn't work. I assumed that entry was bad so I deleted it and tried the second one. That didn't work either.
Here's how I now have it setup:

I also tried this:
MusicBee can see my phone:
I tried the File menu sync, but that didn't work. I next tried to sync an individual playlist.
That didn't work either.
At this point it's clear that either there's some technical problem, I'm doing something wrong and/or I'm missing something plainly obvious.
