iPad Pro 2022 M2 and Acrobat reader won’t open fillable pdf

Trying to open a fillable pdf from a gov't website to assist clients but the file keeps calling for upgrade to acrobat reader I or better.  I download thr file using the Safari browser because Chrome and iOS don't play nicely together.  I then open Adobe reader then choose the file from the files folder on the iPad.  Nothing........Sooooo frustrated.  Works just fine using a PC.  Why?
