My biggest share (25gigs, ~37k files) is spread across 5 computers: Home Desktop: upgraded to experimental. All shares now OK. Work desktop: upgraded to experimental. All shares now OK. Laptop: Haven't upgraded yet. Tablet: Haven't upgraded yet. Home Server: BTSync is running in an unRAID Docker, I am not sure how to upgrade this. My biggest share is OK, two others are not. Will upgrade the others later. So far so good. Thank you.
