Syncthing is terrific – but for some reason my Android instance can receive changes to synced directories, but cannot send changes to those same directories.
For example, I have a shared directory “MySync” on a Linux computer, let’s call it “A,” and have set it to share with the Android, which we can call “B.” I also have a third Linux device, called “C.” MySync is shared among the three devices and none of the devices’ directories are set to “Read Only” in Syncthing.
A & C sync bidirectionally (i.e., files added or deleted in either A or C will propagate to the other device).
A & B sync unidirectionally, with A acting as a “send only” device, though it is not set as such in Syncthing (i.e., A can add and delete files, and those changes will be propagated to B. But any changes B makes are not propagated to A).
C & B sync unidirectionally, with A acting as a “send only” device, though it is not set as such in Syncthing (i.e., C can add and delete files, and those changes will be propagated to B. But any changes B makes are not propagated to C).
Any idea what is happening here? I have tried this with several different directories and different devices. The issue appears to be with the Android client.
