[SOLVED] Changes to user profile not saving?

Hi there,

I am in the process of migrating instances. I have been trying to add a bio and avatar to my profile, but when I press 'Save' at the bottom of my profile settings, I don't see any changes on my profile page.

I have tried this on both instances' profiles, and on desktop and mobile. I don't know if this is an error or perhaps I'm overlooking a necessary step.

Has anybody else encountered this? Any help would be appreciated.

Edit (SOLVED): Changes seemed to push through when I removed the link to my old profile from my bio. Either profiles don't support links, or I hit a character limit. Still not quite sure.
