Clients Constant hdifficutly with Theranest Portal

Wondering if anyone else experiences difficulty with new clients accessing intake and forms? Today, I had yet another new client say that she could not advance to the other forms after she completed one. The portal would not let her advance to the next set of forms. I would say that at least 8 out of 10 new clients has some sort of difficulty with the portal. Is it me? At first I thought it was the client, but now it’s been several years and still no change. Sending them a video from Theranest is not helpful. I have pretty high functioning clients so not sure what the issue is. Has anyone else had complaints from clients? It’s really annoying because it takes up a lot of my time.
