I wanted to add my steam account but it says that the link isn't working. I tried many different options with the numbers at the end of the link and my username. The link i get when copying from steam isn't the same as the sample one so i also tried editing it to look like the sample link. No setting in my profile is on private so that shouldn't be the issue either

Edit: when i add profiles/number it shows a different account but not mine so i know that it's technically working just not with my account

When you're on your profile on Steam, in the upper left corner, what is the URL?

Here is what mine looks like:

https://steamcommunity.com/id/jwcooley/

On my account page, I put jwcooley in the text box for the Steam line.

I'm not 100% certain why you have a number if that's what's on your URL.
