I wanted to use Here WeGo as a second option for Pure Maps, but the latest version didn’t work well with my new Jolla phone. Typed text wouldn’t show until I hit enter and any button took 5-10 seconds. I downgraded to 4.17.200 (48576030) and now the app works well. Version 4.18 already had the same problems as the latest one (4.20.110).
Sharing in case it helps someone with the same problem.
