To: Adobe Acrobat Android app (I was / am using Version 21.10.0.19961) developers / managers ...

re: Adobe Acrobat Android app document sharing permission sneakily grabbed from me during opening of Canadian Federal 'VaccineProof.pdf' document:
My feedback within the app (when prompted to chose an app to provide the feedback, I was presented with the most recently used e-mail app[s], ect. ... when I was prompted to swipe up for more app to use options, the A.A.A. app arbitrarily accepted my feedback w/o me having intentionally selected any particular app [that I was aware of] ... by what means did the A.A.A. app share the feedback?):

"I intensely dislike being forced to share my document with Adobe ... when the notification GUI pops up, there is seemingly no other option (if one wants to actually look at their document) but to click on the 'Continue' button ... by that point, the sharing deed is essentially done with no other option(s) or way back to a prior Adobe Acrobat app non-sharing status state.
Tell me how to withdraw both my shared document, and, my permission to share documents with Adobe!
If you do not comply or ignore my message here, I will discontinue use of the Adobe Acrobat Android app entirely!"

I am a 4th year B.Tech student Rajasthan, INDIA. Due to pandemic, I gave my online exams for the seventh semester in the month of January this year in which I scanned my copies using adobe scanner and submitted to the respective Google forms. Now my college authority is denying the submission of 3 out of my 7 papers and are penalising me wrongfully by failing me in the semester and I am asked to repeat the entire year again. I have been begging/requesting them to check their records to see that I have indeed submitted my responses and may be because of a technical glitch it is not showing up in their database currently. I have been asked to provide the copies with exact date and time authorized by Adobe as a proof. So I request you to kindly look into this matter and give me the proof with exact date and time of my scanned copies. This would help save my career and would restore my faith in technology.
