Our Xperience by Kentico site is using a few different page builder page content types and all work fine except the home page. When clicking the Page Builder icon in the admin for the Home page it's just a blank screen. All other instances of page builder pages load the standard UI with gear icons for editing etc. As best I can tell this has something to do with being set as the 'Home Page' in the channel settings. If I set the path for the home/default page of the site to a different page then I can see the page builder on the Home page and the newly selected becomes unview/editable. In Chrome dev tools I can see the URL path of the iframe content appears to 404 when selected as the home page, something like (with some obfuscation in case it matters but mostly just guids and generated number strings)
websitedomain.com/cmsctx/pm/GUID/lang/en/wpid/####/cid/#/cdid/#####/readonly/#/pbmode/edit/h/#######/-?instance=GUID&uh=#########
When I swap the 'home page' channel setting to a different page, when the page seems to work as expected, I see
websitedomain.com/cmsctx/pm/GUID/lang/en/wpid/####/cid/#/cdid/#####/readonly/#/pbmode/edit/h/#######/-/home?instance=GUID&uh=#########
Note the difference of '/home' in the second path. If the page builder became uneditable for all instances of a set home page then I imagine I'd have come across the problem before when searching the community but I've not come up with much. This makes me believe we must have something in our environment that's causing the path change but as it's seemingly controlled by the channel settings I thought to ask here in case there was some insight. So, please advise and give any recommendations on how to resolve or where to look.
