Fillable form completed on iPhone shows blank on Windows 10 Reader, but prints ok

My wife completed a fillable form on her iPhone and emailed it to me to view on my Windows 10 PC with Adobe Acrobat Reader.

When I view the form in Adobe Acrobat Reader DC, it appears blank, but if I print it, the fields are populated.

When I view it in Firefox, it shows the completed fields.

When I view it in Microsoft Edge, it shows the completed fields.

So, it is only a problem with Adobe Acrobat Reader.

I tried some of the tricks posted on the forums such as adding a space or Cut-paste, but nothing works.

From viewing these forums, it appears this issue has been reported for at least 8 years now.

Will Adobe ever fix this problem?  I understand, Adobe wrote the spec on PDFs, but apparently everyone else is doing something different, so it seems Adobe needs to adapt.
