App Adobe Acrobat v. 19.3.0.9016 under Android 9 on Samsung Galaxy S10e has problem with scaling QR codes in pdf files. While in "continous" mode, and trying to enlarge image of QR code, it comes out blurred, not sharp enough for QR reader. Attached problematic files and printscreen of problem itself. While opening the same file with pdf reader from Google problem does not occur, also attached.
