Unable to save to syncthing: 0 files copied to Syncthing

[franzos]

Here's what I'm doing:

1. Open the share dialog in any application
2. Select Syncthing -> new dialog opens "Save to Syncthing" (No sub folder is selected)
3. Press "Save"

Message: 0 files copied to Syncthing followed by an error message.

This has been happening for 1+ year on my Android 8 device and I assumed it's a problem on my end, but it continues to happen on a newer Android 14 device, so I decided to report it.

Version Information

• Syncthing v1.27.6
• Android 14 Graphene (and Android 8 Vanilla)

I've been using another application "Save locally" as workaround.
