Hi, when I download an Adobe document it automatically saves the document with the extension in big letters .PDF instead of .pdf so I began to have problems to print. Sometimes the printed looks like encryped/garbage characters, I suppose that the extension problem could be related to that problem too. Now I have another problem, when I tried to attach a scanned document to a on-line form it said that the format was wrong. So now I have to rename ALL new Adobe documents to be able to use them. I have to mention that it happened when using an Android Samsung Tablet that I use as a Phone too, it's a very recent one, GALAXY TAB S9 5G, One UI 7.0,  Android Version 15.  I would be very grateful for any help. Best regards,
