Hey,
I’m in the same situation. Fortunately @ddubyat compiled a compatible file with the up-to-date minor version of syncthing (see Request for 64k binaries).
After installing you will run into the problem that MyCloud will “reset” the custom configuration on every restart, so your setup with autostart etc is not persistant. My workaround is to activate Dropbox in the admin panel and edit the Dropbox startup script.
