Crashes all the time

What happened to this app? It was amazing and now its just impossible to use. Almost 90% of the time I just open the app is an instant crash, not to mention other critical problems like syncing and over slowing everything. This app was amazing, now has come the time to uninstall it.

Update: After a big frustration, trying to use once and again this app, I just gave the try to a new app (not naming here). Best decision ever! I dont know what happened with Airmail, it was a wonderful client in the beginning, but now, now Im gone, probably forever.
