Make sure that your maps are updated. Check the data version in the app (CoMaps icon at the bottom left). It's in the format YYYYMMDD (year, month, day). If you made your edits before this date, please report this issue. If you made them later, please wait for the next map data update.
I’ve made corrections in OSM, but CoMaps is still showing incorrect information/routes.
