This is my take on your question.
If you need support::
- Create a New Topic
- Category: Support
- Tag: pamac
If you want to provide feedback:
- Create a New Topic
- Category: Feedback
- Tag: pamac
If you want to report a bug:
- Go to gitlab.manjaro.org > Applications > pamac > Issues
Although it could also be pamac-cli, pacmac-qt, or even libpamac
I suspect you might have been looking for a big button on the Support page. I think those big buttons are sub-categories, and they are the second item in the filter at the top. At this time, there is only a tag for pamac.
As far as getting updates, I use pacman and pamac only for the AUR.
There is a sub-category for pamac under Manjaro Development. I’m not 100% sure, but I believe it is used by developers to communicate to the community. There is nothing in the About other than links to gitlab.
