I simply cannot go through sign in process. After credentials,there is captcha and after that verification code that arrives but the screen never loads. Sometimes it shows "Something went wrong" message. App completely unusable due to this bug. EDIT: After setting 2FA via Authenticator and clearing cache/storage as suggested I was able to log in. Thanks for assistance. One thing I really miss out of the box is search capability. Hope it'll be added in next updates.

After 5y of development Proton calendar android app is still missing a search functionality to find calendar invitrs and you cannot e.g edit reoccurring meeting invites received from Outlook. Also saving new calendar invites is quite slow. Update: Thx devs for the response, good to know that search is being worked upon for Proton calendar android app. Bumping score to 3.

Perfectly functional on my phone, but it only works in portrait mode, so it's pretty useless on my tablet. Uninstalling from tablet until this fault is fixed.
