Hello, I just renewed my subscription.
I also never got a helpful response to this issue... and now several other parameters don't seem to be saving, even after all the updates and Joomla being updated to 5.4.1.
We have 2 JA Impact Site Template Styles. The one that is Default says that it is assigned to all pages, but several of the sub pages don't have the style applied. When I try to change the Subpage Layout dropdown to something like default, the setting doesn't persist. It goes back to sub-detail.
Also, none of the changes I make under the Menu Assignment will stick.
