How to ruin great app with an upgrade

This app after an upgrade is sadly very disappointing!
Losing data, switching off, logging out. Yesterday I had 6km distance as it is my standard route. Around 4th km phone rang I talked, hanged up and it appeared that distance disappeared and only time is left! (Sic!). I do not recommend it even tough it was the bast app BEFORE AN UPGRADE.
