We have seen a new issue that is related to the latest update. The issue is breadcrumbs on doc library and lists where any user can see everything. We want to be able to set permissions where only admins can see a specific set of documents/list items. With the new add we lost control of what we want people to see and want less to see.
Life was so much simpler when we had the classic site, and we could build it the way we wanted on the front end of the box and could use W3 CSS and didn't have to put up with visual studio code. Bring back the use of SharePoint Designer so we can build premium forms and sites. Team Foundation Server is so old and doesn't provide the capability like we are used to. It reminds me of the issues we had with early SharePoint Designer and forms. The term low code is so not the case. It seems like the only code that is low is Microsoft. I was building custom forms in Designer that took minutes and now takes hours to do the same thing. Bring back designer, I need to get things done.
