New KMB file format created by Maps.Me

[Rosita]

After updating my Android system some of my bookmarks were lost (those of two years..) I found them under mapswithme/bookmarks section but all of them are in *.kmb format and I cannot find a way to add them back to maps.me. I was trying to convert them to different formats on my computer (*kml.) but that still did not work even after converting. Would you have an idea of how I could solve this issue, please? The example with Decatlon stores in France worked for me. So I think I am converting the files wrong, maybe I am using not the right programs which mess up the data.. Help!

Thank you,
Rosita
