I tried to add a new service of Slack on Franz and the page appears blank and doesn't have the place to log in. What shall I do?
Can you please update your initial issue with all the necessary information like macOS version, exact Franz version and so on. Please use this template, it makes tracking and reproducing issues much easier.
The same happens to me
Slack doesn't load when added as a service. Tried readding, Ctrl-R, restarting the app, etc.

Solved. I was missing the team on the service settings page.

Our team as ADFS login system. And I can't ever use this team in Franz. That's very unfortunate. :(
