I have been using an editable subgrid component on a Power Pages basic form. It generally functions quite reliably on Chrome / Edge browser, whenever inputs / edits in the grid cells are made by the user, the changes take effect immediately and saved into Dataverse.
However in Safari browser, the component seems problematic. Most of the time, the edits are not saved and the key functionality seems to be intermittent. There is also a series of error messages in the browser console log, specific to the operation of the component. I suspect its browser-specific compatibility issue.
Was wondering if anyone encountered similar issue with this component on Safari, and if so, can advise if there are possible workarounds (e.g. adjusting Safari settings)?
