Error "deN, code: 12521" when migrating from LM 3.1 Pro to LM 4

[Frank]

Hi,

as a long time user for LM 3 Pro I wanted to try LM 4. When migrating, the transfer aborts with the above mentioned error after a few seconds. The last string I see before it aborts is something with "waypoint". The same thing happens when I start the migration again from the Settings menu.

Device is a Google Pixel 7 with Android 13 and tons of free storage space. LM 3 data is stored in /storage/emulated/0/Android/media/menion.android.locus.pro

What can I do?

Regards
Frank

Hello Frank,
sorry for the late answer. This seems to be probably the most common error when transferring data that we were still not able to fix. It is a generic error where we usually need a big log created right after the error happens. Thanks
