Up until recently, it was a quite painful experience to edit Tempo accounts in next-gen project issues, because the field was not available on the edit issue screen.
A suboptimal (yet functional) workaround was to use the bulk edit interface and edit the issues in bulk even if only one of them needed to be edited. This was annoying, but it worked.
It would however appear the tempo accounts field has now been removed from bulk editing as well, making accounts entirely unusable for next-gen projects, or in other words, making Tempo entirely unusable for next-gen projects.
I've tried changing the features and "apps" settings for the next-gen project, to no avail. Other than setting a default Tempo account for new issues, I have found no way to change the value for existing issues.
Is there another known workaround ?
