Hi,   I upgraded my application from version 9.14.1 to 9.24. It is mainly based on non-persistable entities. The basic setup is like this: A page, eg. “publisher” contains data grid 2 with a microflow as a data source with info about associated entities, eg. books. On click on a “book” entry another page with detailed info about that book is displayed.   The issue is with the “Back” button, which should just display the “publisher” page. While this worked flawlessly in version 9.14, it has a very poor performance in version 9.24 and takes a minute or so to display the page with the progress bar shown.   Have their been any changes on Mendix side or how can find I out what the app actually doing that takes so long?   Thanks   EDIT: the following error message appears after some time:
