Thanks to @IzzyOnDroid@floss.social the reproducible build of OSM Dashboard for #OpenTracks is now fixed. And, as a nice addition, also available on IzzyOnDroid F-Droid Repository:
https://apt.izzysoft.de/fdroid/index/apk/de.storchp.opentracks.osmplugin
I think the build for the official #fdroid repo is also fixed, but needs a few days more to be available.
