It seems Moon+ Reader Pro has changed its settings and even the FAQ on their site has not been updated. When asking how to sync Moon+ Reader Pro across android devices using GDrive or DropBox the answer has been to go into Misc Options and press Sync, then choose either GDrive or DropBox(or hit the gear next to one of them first. Then hit Sync Button.. I forget.)
But anyway, now there is no Misc Options setting to go into. I can get it to view the files on GDrive, but I see no Button or other setting to sync the reading position never mind files. If I have to run Calibre server or manually copy the Caliber Library onto the devices that is no big deal. But it would be nice if I could set it up to remember my bookmark when I open the same book either on my phone or tablet.
I have Marshmallow on my phone and Lollipop on my RCA tablet. Both devices have a populated bookshelf. After messing around with GDrive I just copied the Calibre Library over a USB cable on each device to get things working.
Any help with syncing would be appreciated.
