Hi @sdaniel ,
Could you please share a bit more about your issue?
Do you mean that the Choice field in your SP list could not be displayed as options to select in your app?
I have made a test on my side, and don't have the issue that you mentioned. Please check if you or other users (who have edit permission to your SP list) converted the Choice type column in your SP list into another column type, e.g. Single line of text column.
In addition, please consider take a try to re-create a new connection to your SP list from your app, then check if the issue is solved.
Also please consider take a try to re-generate an app based on your SP list, then check if the Choice type column could be displayed well within the Edit form of your app.
Best regards,
