Authentication Access code required: Never arrives

Hello,

I recently subscribed to Adobe, i.el three mos ago.

To date, I am unable to even sign ir fill in a PDF because the system wants to send me a verification code.

It's been three hours so far. I resubmitted. Nothing. These past several weeks I[ve been reduced to printing, signing, scanning & emailing rather than a simple PDF. 

One code did arrive, a week later. Help? Thankhou very much. Off to print the document to manually fill in with a pen.

It may arrive next week.
