This is related to Something went wrong when installing Connect App but more serious.
We noticed errors when we tried to install our own apps (e.g. ZenUML Diagrams for Confluence | Atlassian Marketplace) for test the above errors. What made it more weird is that I received emails telling me the the app was installed, but I cannot see it when I tried to add a macro.
This is a lot more serious than the previous issue so I created this new topic.
Can someone please help us?

Peng
