New
I've got an account linked with Google account (lexuandinhct). But I cannot create new topic using that account because it recurrently redirects to the signin page, as shown in the attachment video. I've tried changing browser (Chrome, Firefox, Edge) with no luck. So I tried creating a new account linking with Facebook (this account lexuandinhct1), and luckily now I can create a new topic!
The same problem
