OK installed the update, same problem, even uninstalled and reinstalled and still the return key doesn't do anything :/ Sorry to make you more work :D

update might not be live yet in google playstore... I submitted a couple of updates. it will be v2.0.2.1 and they roll out slowly with playstore. Notice the "Current Version" section. With my playstore it still says v2.0.2.0 (which was yesterday nights bugfix)...

Success! Not sure why it offered to update me earlier but I saw the version update just now and imported my keys with no problem, thank you!
