Tiktok Instagram Button is gone

On one of my Tiktok accounts my Tiktok button is gone. I tried connecting my Tiktok to Instagram and then it failed somehow and now the option to link it is completely gone!

I tried to reinstall Tiktok, but it did not help... its now since one week like that.

Otherwise the account is running very good, a few Tiktoks reached around 100k views... but bad conversion like this..

Did anyone experience this too or knows how to fix this?

Clear your TikTok app's cache and data, or try downloading on another device to check. If it persist, contact TikTok support.

Delete your TikTok app and reinstall it, if it doesn't work, contact support.

Try deleting it and reinstalling it
If still doesn't work, reach out to the support team, bro
