Locus Map V3.66.0 - Track Visibility Keeps Turning Off

[Alan]

Just updated to V3.66.0 (Samsung A72 Android 13). There seems to be a problem with the track visibility. All my tracks had their visibility turned off.

I turn the track visibility back on for some tracks & then close/shutdown the app. After opening the app again, all tracks have their visibility is turned off (including the ones I just previously turned on).

Is anyone else having this problem?

I have no problems with track vivibility (A52 Android 13) in V3.66.0.
My settings and changes are kept correctly after a restart.

Interesting, I also do not have this issue. How are you closing the app? It needs a few seconds, so the best how to test it is to close it by double back click + wait 5 seconds before starting back again.

I'm pretty sure I gave it a reasonable time to close (swipe off the screen etc). I also noticed it was taking longer on start-up because it was searching through all the maps (approx 100 mbtile maps) every time I closed & launched it. Previously, it seemed to learn the new maps & subsequent starts were much quicker.

I have most of the Locus Map data (Backup, maps, mapsVector folders) on the micro SD card instead of internal phone storage. I previously used the "Set custom sub-directories" to point them to the micro sd card's Android/media/menion.android.locus.pro/Locus equivalent folders.

Perhaps something had mucked up with the micro sd card. Since no one else is having this problem, it seems specific to me (& coincidental with the 3.66.0 update).

I tried using Backup manager to save my tracks/points/settings to both the phone storage & the micro-sd card (changing the backup location through the custom sub-directories)  In both cases, it kept saying "unsuccessful" (or something like that) in an orange box. Interestingly, it moved the existing backup files between the phone storage/micro sd but it couldn't write a new backup file.

Fortunately, I had recently backed up my track/point,settings data & maps for use with NoxPlayer to run Locus Map on a PC.

I removed & reinstalled Locus Map via the Play Store & then used Backup manager to restore the tracks/points/settings from the PC's NoxPlayer Locus Map tracks/points/settings.

I set the custom sub-directories back to the micro sd card (giving it permissions), reloaded all the maps & it worked (including the fast startup after learning the maps). So I'm not sure what or why it stopped.

The moral of the story is to keep backups for when something goes awry.

Time will tell if something else is misbehaving e.g. maybe the micro sd card.

Thanks again,

Alan

Just a follow up.

A friend had a similar problem as I did i.e. the track visibility turning off & not sticking after closing Locus Map and then reopening.

I'm reasonably sure it's related to the problem described:

We applied the suggested "Most reliable solution" & their track visibility is now working properly.

Hi Alan,
I just wanted to point you on the exactly the same topic. Sorry for this. Mystery issues happen with terrible consequences. I'm glad you were able to fix it. "Most reliable solution" is what Google pushes and what will work for sure in the future.
