LoMaps on Wear OS 3 watch - issue

Hi,

last weekend I went for a hike and had issue with the maps on my new OnePlus Watch 3, while using Locus Map Watch application. In general the application worked in a way that I could check the recording statistics and it was drawing the route recorder, however the problem was that I couldn't see a map at all - blank space like I'm on a desert. I tried to play with a lot of settings including permissions, but nothing worked. Only at the end of the journey I tried one thing which worked and realized that, when I used offline Lomaps from my smartphone, then the screen was blank and map not drawn but when I switched to online version, then it suddenly started to work.

Therefore my question, is there any issue with sharing local/offline version of Lomaps with the watch? Or it could be something else? Would rather use offlive version as it's already on the phone and sometimes there's no stable network available. Can you advise something?
