All tracks invisible

Hiding the tracks probably occured when I started 4.28.1. So the tracks were already hidden when the fix was in place. I already went back to 4.27 and restored an old backup. But thanks for confirming the fix. So I can upgrade to the most recent version now.

Nope, after upgrading to 4.28.2, tracks are all hidden again. Even restoring the very same track backup into 4.28.2 makes the tracks invisible while in 4.27 the same backup keeps them visible like they were when creating the backup (incl. those who were hidden as well).

Understood. But when I make a fresh install of 4.27 and restore a backup, visibility is fully restored too. When I THEN upgrade to 4.28.2, shouldn't visibility remain as in 4.27?

No, because there is a conversion between two versions of My Library and the visibility status from the old library is probably not preserved.

Anyway, would you please send the backup for a test? The main dev has informed me that he actually found something and your backup file could prove the indication (leading to a fix of this). Thanks!

Sure, you want me to send it in here? Or is there a more confidential way? I mean, these are walks and hikes that I actually did.

I opened a private ticket with a link to the backup file and this ticket. Unfortunately the file was too large for any kind of attachment in an email or inside the ticket. (>120 MB)

Worth for me, yes. Easier, no. I've been using the feature of making tracks visible or invisible since I started using a paid LM more than 5 years ago in order to distinguish routes I hiked from those I haven't hiked yet. It's almost like a hiking diary to me. We're talking about a high 3-digits number (including future ones), not just a few ones. Sometimes that's also hiking-wise one of my major preparations for returning to a previous hiking vacation because it shows what I wanna do or what I still wanna do when I get back to the place sometime later. There can be years in between which makes it hard to remember what I already did especially when tracks are close to or merely variations of each other. That's my motivation. Please understand that I won't discuss whether that's a reasonable one (which I'm sure you guys won't). It's what I do and it's why it would be a pain in the ass for me if I'd loose that yes/no information without a chance for recovery - even if it means going back to a previous version, restoring the backup incl. visibility info (which works up to this point) and installing the update again with a fully restored library (which does not work so far). On top of it, it seemed I can't install the version from the store once I used an archived apk. So restoring my backup into 4.28.2 from the store AND thus restoring the visibility information will be vital to me.
