I built a Power App to be an all-in-one K-12 Physical Therapy documentation app. It's pretty spiffy.

Now if you look at that red circled part, that's a Rich Text editor that absolutely refuses to let me use it. Every time I open app as a user, it's always grayed out (as if it were "Disabled"). However, I guarantee it has every reason to be "Edit".
Here's the details:
- It resides inside of a card in a layout control:

- It's "DisplayMode" settings are: "Edit"
- The Card itself has a complex "DisplayMode" with a lot of conditionals, but I have tested and they all resolve to "True" and "Edit"
- When I create another simple Text Input control inside the same card, it works.
- When I create another Rich Text Input in the same card, it also does NOT work. There is something about rich text inputs inside this particular Card
- I have another Rich Text input sitting in the card right below it ("Objective Notes Free Write") that has no problems at all, even though it's basically in the exact same situation.
Has anyone else experienced rogue Rich Text inputs going "disabled" for no reason?
