Append-Only Comments field on a Modern UI list doesn't preserve a Modern UI list edit and view experience
When adding an Append-Only comments field on a list with the Modern UI, changes the New, Edit and View form to the classic form experience. Removing the Append-Only Comments field, reverts the list back to a Modern UI list form experience.
It would be good to incorporate the Modern Comments ability to a list item as a setting to enable Comments on the list items which behave like the modern Comments in SPO.
Yeah this is very janky at the moment. One single state change switches your nice modern list authoring experience into an old school gross one...
It would be great to understand when this feature is planned to be included in modern?
The support page describing when List view is modern or Classic does not go into the details of when NewForm or EditForm is reverting back to classic as is the case with Append changes enabled Multiple Lines of text column. https://support.office.com/en-us/article/differences-between-the-new-and-classic-experiences-for-lists-and-libraries-30e1aab0-a5cc-4363-b7f2-09e2ae07d4dc
