Yes, they seem to be stripping the affiliate links from some bios. I noticed that when helping someone set up theirs a few months back. Was working but then when I went to update it at one point it no longer would take the link. If I remember right, it turns it into a link to their page instead without the affiliate code. Some models still seem to have them though. Not sure why some and not others.
In her case, I thought that maybe it was because she's using a studio account. But I'm guessing that yours is not?
Her affiliate link does still seem to work. At least for existing conversions. When I buy new tokens, they do still appear in her revenue. Just won't take the link anywhere in the bio.
Another odd thing that I've noticed is that I no longer have an "Edit Bio" link in my own that I use to test for some who I help. I have to use a roundabout way to get into it using the direct link. Need to contact support to see what's up with that just haven't yet.
