you made your acc on may 24......worst case scenario you have to wait for your acc to be fully registered for a month........better case scenario, maybe a week?
I dont think you not being avle to post links is connected with you verifying your acc. Maybe your acc is still being processed if you created it a few days ago
I log in woth my google acc so idk.
Also when did you change your pfp
Settings -> Security &Privacy -> Phone verification
