I primarily use Firefox, but it seems that linkin.bio doesn't work well with the browser. Every time I try to add links on Firefox I'm told there's a network error. If I switch over to Chrome, it works fine. It's frustrating to open up a new browser just to add the links.
Same issue for me. Worked in Safari, though, so I wondered about extensions.
Sure enough, if I turn off Facebook Container, it works again. Since Instagram is part of the FB network, the plugin was blocking the cross-site connection.
Hope this helps – and I hope it finds its way into Later's Support KB.
FF 84.0 / Mac
Safari 14.01 / Mac
