Description Of Issue

Everything worked really well until build 521. Nucleus+ took many tries to update to 521. Progress speed was in the bytes per second range (no kidding). Sent you my logs after your requests, and never heard back. Finally sat up one night and kept prodding the thing to stay connected and the update eventually happened (hours and hours). Copying files to Nucleus+ internal SSD slowed way down when transferring files to it, but would complete the copy. Playback was OK.
Now v571. Download took forever again (hours and hours). Babysat it and eventually it installed. Since 571, audio devices will stop playing every 3 to 10 minutes for 5 seconds. Playback bar will stop in client (iPhone, iPad). Five sends later bar will jump to new ‘5 seconds later’ position and start playing. Went to add audio files to internal nucleus+ ssd, and no hope. Can create folders ‘quickly’ in mounted drive storage area, but then adding the actual files dies on the vine. Progress bar just sits at ‘calculating time’, with no progress. Hitting ‘cancel’ on the copy takes close to 8 minutes to actually stop the copy dialog.
I’ve done the usual re-boot, etc, no difference. Doing a manual backup seems to work fine.
Now what? Any clues?
