Sounds more like it may potentially be a bug. I've moved this to the troubleshooting forum, but you may also wish to open a support ticket.

As the conf file is essentially a JSON file, each line in a section (apart from the last) needs to end with a comma.

There is - you can enable debug logging. Do be aware though that Sync can't sync files that are open/locked/in-use by other applications - which may be the reason why some of your files are not immediately syncing

The "folder_rescan_interval" advanced setting can be used to set a recurring interval at which your folders are re-scanned for changes. If changes are not being picked up automatically, this regular re-scanning setting should pick them up.

The team are aware of this issue and are working on a resolution - please see this post.

Have you tried unticking the "Show notifications" option (Settings -> General), and changing the advanced Power User setting "enable_file_system_notifications" to false?

Don't worry - 2.5 will come to auto-update in due course. New builds are always announced here on the forums in the first instance and initially only available for manual install/update. The main reason auto-update isn't usually enabled at the same time as a new build is announced here, is to allow the team to capture any significant issues from the sub-set of users who manually update, that perhaps weren't picked up in testing/QA phase, before pushing a new version out to everyone. Typically it can be anywhere from a few days to a few weeks before auto-update is enabled.

Is it possible that you entered the key incorrectly? Where did you obtain the key? If it was copied & pasted from an email, did it copy correctly? (i.e. if the link/key "wrapped" onto a new line in the email, when copying it may have inserted a space/copied as two lines instead of one, etc)

Did the port number change? (Settings -> Advanced -> Connection -> Listening Port) if so, perhaps your firewall is blocking it? See also: https://help.getsync.com/hc/en-us/articles/205450205-Peers-aren-t-connecting

Sync 2.5 now includes the ability to "filter" your folder list by "All", "Connected", or "Disconnected" folders. Selecting the "Connected" filter hides all your disconnected folders from view

You misunderstand - I said any "user" (i.e. a user of Sync) can receive an individual file. Sync is still required

Folks, Sync 2.5 is now available which includes "improved IPv6 compatibility"

All, I'm happy to report that Sync 2.5 is now available which includes the ability to both sort and filter history!

Folks, I'm happy to report that Sync 2.5 is now available which includes the ability to share individual files! (Pro users can "send" individual files, any user can "receive" them)

You appear to have originally joined in July 2013. At that time, Sync was part of BitTorrent Inc. BitTorrent Inc's forums were previously hacked. Resilio have since taken over development of Sync, and those parts of the original BitTorrent Inc forums relating specifically to Sync were transitioned across to these new Resilio forums. Users who signed up on the original BitTorrent Inc forums prior to 1st February 2016 are able to use their previous credentials to login to the Resilio forums. It's important to note that Resilio's forums themselves have not been "hacked".
