I have spent 2 days ready forums on this site related to this issue and none of them have been able to help do what i'm trying to do. I'm sure its me. but...
I have a large Sharepoint list that has users and applications they have installed among other fields. So far, I have a Power app, that, when a user opens it, onstart filters on their email. So they can only see their apps. So first screen looks like below:

When a user clicks the chevron, it takes them to an edit page like below. This is where I am having issues. My goal is for the user to click yes, or no, then have the text 'Yes' or 'No' populate the associated column. So in the example below: there is a row in the list with the users email: f.l@company.com, App: Adobe Acrobat, Do you need the app? (single line text), etc.

From the research I've done on this site, I know Patching is involved. But none of the solutions I have tried have worked for me. The SP list never updates. I've tried changing the column to single line text, so it can enter the string, but to no avail. Changed to choice (y/n) column and tried boolean patch method, same result. I would share code examples of what I have, but I have tried so many different methods, I wouldnt know which one to provide. None worked for me.
Any assistance with code/images would be greatly appreciated!
