I noticed that when I add YouTube to my social media connections, the link has "/user/" which YouTube doesn't use anymore for newer accounts. Please change it to "/c/" so everyone can connect their accounts. Also, for the Spotify connection, it puts "/show/" instead of "/user/" in front of the link.
For spotify, there are two options you can select; I believe the "show" one is for podcasts. For the youtube URL, you should file a bug report via the support hub.
Only legacy URLs work for YouTube https://support.google.com/youtube/answer/6180214
If you have over 100 subs you can just have a link of link your custom url. For example: https://youtube.com/sizzyl or https://youtube.com/szylyt
@Sizzyl I have a custom URL, and it still sends me to a /user/ page You must of changed your social media a while ago when it was working
After putting my full url, it works xd
Appently you need a c/ infront of the url
