Thank you for your reply. I tried to upgrade to Locus 4 again via Locus Classic but failed. I encountered the same 11556 error, which makes the app completely unusable. It seems that I have to uninstall it and the app data can't be retained during uninstallation.
I have also upgraded to a Silver Premium.
I have a huge number of points and tracks, and I'm not sure if that's the reason.
Since Locus 4 will continue to be upgraded, while classic may stop being updated altogether, I estimate that this problem may persist for a long time. Furthermore, each user's data and custom directories may be completely different, especially since different mobile phones and system software versions are also different.
So, could you provide a guide on manually transferring this data? Because it's been used for so long, I don't even fully remember what data and personal settings I have; I only remember some of my most important data, which includes at least:
1, points
2, tracks
3, Calibrated maps etc, include all Map items( In Locus 4, it seems that Map items are no longer available?)
4, I also have my own online map configuration file, and I don't know if Locus 4 supports it directly.
5, I also downloaded global altitude data.
6, There are also several huge offline map files.
So, could you please provide a manual transfer guide? Many thanks.
btw, I found that OsmAnd can almost freely search local map data, a feature not supported in the classic version. Also, OsmAnd's local data processing seems to be very fast. I look forward to these details being improved in the future.
