I am working on a project. I installed an integration a week ago. Since I have had nothing but trouble. Uknowingly that integration is the one causing the issues. Now, when I click manage, it takes me to a 404 error page. So, my fix is there should be an add and delete integration button for integrations. Not just a manage button. IF Vercel had an "add and delete" button for integrations that would override the "integration management" on your system, this problem would be null and void.
