I completed a document in Adobe Acrobat Pro 2020 using form fill and edit document. At the end, I saved the document as a PDF. But upon opening the document the following day, all the first letters had become invisible (still there just not showing), and entire boxes of text and numbers had also become invisible. As per other discussion threads, copying the invisible text in each box and repasting it in a new text box causes it to reappear, as does changing font, but, my point is this... I SHOULDN'T HAVE TO. I haven't converted the document to any other format or done anything unusual. Even more baffling is when Adobe Acrobat decides to alternate the cApItAl LeTtErS in words. WHY???
Solution: I opened the Adobe PDF using MS Word and it was fine. REALLY??? There has to be a solution as this is a serious failure in a program designed for handling pdf documents.

Sorry, I've been out of action with COVID since I posted. The file I had problems with recently was confidential, but Adobe has since butchered another file in the same way and that one is not private.
The faulty section is shown in the image and file is attached. The highlighting is where the text has"vanished". Changing the font makes it reappear.
