If I have missed the answer to this, my apologies, I've searched and searched and found nothing.
I have been using JRiver for years and years, but don't interact with other devices often - typically for a sync of mass music with and new device. I haven't upgraded beyond version 22 as I just felt there was no need to at this time.
With my recent acquisition of a Samsung S22 phone, I am going non-SD card for the first time ever (for a phone). I had a previous playlist curated for my old S10 which I used to sync with. I renamed it and tried to tie with my phone. It was just too much and crashed the software. So I created a new playlist to sync with and am trying to slowly add more songs to it. Upon recheck sync, I currently find it putting songs in the "In Queue" which are already on the device and then error out when trying to process. (Windows 11 pc)
Another issue is that while I'd love to delete what's not in the selected playlist and go slow and clean, I fear it will delete all the core files off my phone as many show up in the JRiver list.
Any answers, suggestions, input is greatly appreciated as I have a HUGE music collection and do not want to rely on the internet to delivery tunes I want when I want.
Best,
The Doug
