Unstable. Can not connect to account.

Any time app starts it cant connect to air services account ("Connection error, retrying..."). You have to erase all user/password data, restart app, enter user data again and connect... until next time you switch from the app.
Unstable. Crushy and slowy.
New waypoint symbols are not useful (giant rings except of stars - hard to find quickly on the map, hard to identify the center point when creating).
Totally new version was published right before xmas - so no any support detected. And no chance to roll back to previous version to use the normal app until this guys return from holidays.
