I uninstalled syncthing-fork when I first heard "foul voices on the air" (LotR ref) because I haven't needed it recently, & decided to reinvestigate when I next need it (& the dust might have settled itself by then). In the meantime someone commented that you can configure & use vanilla syncthing on termux instead. I use termux for so much already that it is the obvious choice (for me) if actually true. If you hadn't heard that either it might be a viable choice for you too...
