So for two months my list form made from PowerApps has been working. I had some buttons (with SubmitForm actions in OnSelect, so to save the form) that had conditionals in the Visible property depending if a Combobox option was selected or not. That was working. Today all of the sudden not working (button was always invisible). I get this error "Network error when using the Patch function: A server error has occurred.". I waited a long time and still the same error, unable to save anything. Unfortunately, I'm not getting any other context as to why this might be happening, only that short message.
I'm quite frustrated, as I have literally not touched anything on this app since I published it. The dissapearing button was the only thing I changed so it always was Visible.
What other things I could check? Sorry if not enough context, but I really have 0 idea what is going on.
