When opening a fillable form in Acrobat. Upon the first time its opened, edited, and saved acrobat states it cannot save the file. No protections enabled. After closing all the prompts and the save window. When you save the file again it saves without a message. The save went through when its re opened. Seems to only happen when you first open the software.
I cannot show much in images because it is private info.

Windows laptop continual update version. If you are a dev. then I have an older email attached to the account different from this one.

1. Save a word document to Microsoft PDF.
2. Open said PDF in acrobat and click Prepare form.
3. Create a field(s) and save this form version of the pdf.
4. Close out of acrobat entirely.
5. Open new form acrobat file and edit it.
6. Press save, or CTRL + S and the message below pops up.

There are no protections on my current document. It only shows the message once every time the program is opened.
