Hi @sven.schatter - DEVHELP is currently being refactored. We’ve been getting inundated with general support questions that belong on the Developer Community despite our best effort of describing what DEVHELP should be used for. General questions need to be posted here, on the forums.
For the special uses of that service desk (i.e. 3LO app distribution applications, email API access applications), hard links are provided in announcements and documentation.
The primary remaining use case for DEVHELP was for reporting critical bugs and issues, which is still available [here]… and likewise, app security incidents can be reported here. Likewise, app security incidents can be reported here.
The main portal is still available at Jira Service Management for the main JSD portal. Again, the removal of the link in the forum headers was due to the fact that we’re continuing to get general development questions that should be posted publicly here instead.
