Hey all - you might want to update your BTSync app... I just got an update on my Nexus 5 ( version 1.3.20.0 ) and I now have syncing over the celluar connection, yeah.. I turned on WiFI again and got another sync ( assuming it was over WiFi ) but I'll be testing quite a bit more now. Thanks BTSync devs... Now I can migrate my tasks/notes fully to todo.sh(linux) and Simpletask cloudless(Android).
