Accounts are "Disconnected"
Sometimes the connection to your accounts can be lost, this happens for security reasons and is not a bug.
When this happens, you may notice that you’re unable to reply to comments, publish content etc. But It is easy fixed, make sure one of your admins do the following steps:
Step 1: Access the Settings panel
Step 2: Go to the Social Media Channels tab --> Click Reconnect
PS. If you're not the Admin of the disconnected page press "Ask page owner to reconnect" and the admin will get an E-mail asking them to follow the procedure shown above.
OBS: When it comes to TikTok, it works a bit differently — you’ll need to remove the page and then add it again for the connection to be restored.
To remove the page you press on the three dots on the side of the account and then "Remove page"
