Just signed up for this issue like others. Been using ST for a while to keep mobile/mac files sync with a 3rd online server as a go between in a 3 node fully synced setup. Been working for months until I got a new phone.
Steps to lose files is too easy imo
Recreate steps
- create working 2 way sync setup with multiple devices
- Add new device (android mobile in this case)
- Share folder with new android device Edit Folder > Sharing > Tick new device
- Accept new share on android, define new directory for this share
At this point the folder will not sync, only option on mobile is override changes which will delete all files from all nodes.
Further more adding files back on any other node repeats the same scenario, mobile stops sync requesting to override changes which as stated delete the files again.
It would seem impossible to sync files from node1 to a newly added (android if it makes a difference) node3 on a pre defined setup without a master (send only mode).
Expected results When adding a new share with a new node. Initial sync performed to bring new node inline with others.
