try just putting a random YouTube video link in it and put on the icon, then when ur done, go to the app and change the url back to ur bio

^^ yeah that's basically what I was gonna comment :)

That just means you need to put .com at the end of your bio. But once you save it, you can change it again with the app. I just copied my bio, deleted it, put in the icon, went back to the app, and pasted my bio back on.❤️
