If anyone forgot to bind a tranfer code, you could try export your save files for one instance (or emulator) to other one. it could help for those whose app is not opening or loading. It also helps as a backup of your account.
Try following the guide on the attach file. (You may need to create the "data" folder on the target device/emulator).
I did it long ago to play the base version on my phone and on PC with the same save and I haven't had any problems. It should works for the modded version. The only thing i can't do is resume a quest I started in the other device. so you could only lose AP(?), I don't know if there is another risk.
If it did work for you please bind a tranfer code as soon as possible and write it down in a piece of paper. Finally, credits to the fellow master who made this guide, vanwayne8 =) .
