The overall quality and speed are below average, the contest tasks are not completed (profile picture uploading is missing, it's not possible to change the password visibility, the monkey animation is looped when entering a code).

It's not possible to log in with certain countries numbers, the app doesn't recognise country prefixes. The design of the app doesn't comply with the provided mockups.
Google Chrome 78.0.3904, macOS 10.15.2

Hello, I’ve added the “try again” message because of this API errors, could not find out why it’s not stable and works after a few tries.

Yes, I could not decide how to handle multiple country codes so made it not inserting country code at all yet.

About other things - yes, really, have not enough time :(
