Is anyone else having any issue with calculations in the modern form designer?  A customer has a simple collection for requesting a PO that calculates totals.  It works when opening the form on a PC but if you try to use it on a mobile device, whether in a browser or the mobile app, the calculation won't happen unless you click "Add".  The mobile device needs some trigger to force the calculation to happen and I'm not sure why.  Is this a bug or am I missing something?  When I test using the classic forms designer, the calculation seems to work so it's definitely specific to the modern designer.  Thanks for any insight.
