What a disaster that app is. I have it and have used it on occasion but the number of errors a quick scan of the page at mmwatch reveals indicates to me that Maps.me is a mixed blessing at best. Folks in the tagging group stress out about the proper way to tag OSM objects in discussions that last days while Maps.me users just tag away with abandon. I’m quite sure most have never bothered to read the Wiki or ask an opinion from other more experienced mappers.
Even if I had the time to contact each Maps.me user to discuss changes I’m not sure it would be worth it. I’m just too busy with other projects. Arrrgh!
