Good evening,
I just relinked my imgur on the Android app and encountered no issues.
May I know if you have received any error messages?
Additional details:
(a) When trying to login with your IMGUR user name and password, (1) ensure that the details keyed in are correct, (2) click on the allow option
(b) If you see a red reset option, kindly click on it before associating your account with the official hwz app
(c) Ensure app is updated on the play store
(d) Try clearing cache and forum activity on the mobile app
