I've send two emails yesterday asking lunchmoney support for help with bugs, but nothing happens. I have no idea how to contact them else: Slack link is expired, no other ways to contact. Seems like there is no support at all now.

"This link is no longer active To join this workspace, you’ll need to ask the person who originally invited you for a new link."

When I next accessed my budget, suddenly the site wrote that it was creating a demo budget. In the non-demo budget appeared categories from the demo, while the transactions I entered in the budget disappeared, the data I entered about budgeting disappeared, the rules disappeared.

In transaction view, when you scroll down past the headers, only the top categories are visible on my screen and the bottom ones aren't accessible

When doing a "general search" you should be able to paste in a number with a comma and still get a valid search result.
