I'm working on a model driven app which uses a lot of different custom activity tables, in a custom solution. Up until this week, I was able to change the fields "scheduledStart" and "scheduledEnd" from "date and time" to "date only". However, as of this week, that is not possible.
I have five custom activity tables from before this week, where these two columns are correct (date only). When I try to do this with the remaining custom activity tables, I get the following error:
"cannot modify the behavior if canmodifybahavior is set to false for OOB date time attributes of a custom entity"
I cannot see any updates in Dataverse or Power Apps that would explain this. Has anoyone else experienced this? Or does any of you know of a solution? There is no mention of "canmodifybahavior" anywhere that I can find. I've tried looking at the documentation, but the only thing I can find seems to say that I need to import the solution with modification enabled(?). But it worked up until this week, so that doesn't really make sense to me. And I don't want to do that until I know this is the correct path.
