I couldn't decide where to put this, so picked Android since the Chrome in question is on a Galaxy S10+.
Having had to factory reset the phone (don't ask!) I am slowly going through the process of getting it back to working again the way I had it. One of the things Chrome did before was fill in some user names and passwords automatically. I have checked in the part of Chrome where the Password list is and the information is all there.
However, the next part - putting the information in the boxes when you visit the sites - is not happening.
Any suggestions to get that to work again?
