Attached screenshots confirm map source still works fine on my old phone still running 3.37.2, but on the newest version the map source is scrambled for both online and downloaded sqlite maps offline.
What must be done to correct this?
Have you deleted the Locus Cache ? (Part of misc settings, I believe)
yessir tried deleting the cache. I took a Titanium Backup of the app on my old phone and used that to roll back to 3.37.2 on my daily driver, maps work again. Seems like maybe there's been a change in the logic governing how tileserver URLs are parsed?
Maybe this post should help: https://help.locusmap.eu/topic/strava-heatmap-requires-now-authentification-at-higher-zoom#comment-70872
That looks to have fixed it (other than now seems I'm waiting for the next update to fix the new download bug for non-256x256px tiles). Thank you sirs!
