For personal reasons I haven't mapped regulary since July.
In between, I have also replaces my phone (for a one with more memory available for mapping. Yeehaa!)
However, now the app says that my flow is empty.
I mapped a km or so the other day, but it still says that my flow is empty, and my contributions haven't showed up on the map either.
Today I drove ~30 km or more, but it still says that the flow is empty.
What can be wrong? And should I continue mapping?
