The title pretty much says it all. I have noticed this happening with most - but not all - sites on which I have log-ins. In addition, often when I do log-in I’m told there has been a security error, refresh the page and try again. That always works. This has only happened with maybe the last couple of updates of iPadOS 16. I’ve already searched the web - including Apple’s community site - and none of the suggestions work. I have not changed any of my settings. A couple of other iOS users who I know report the same thing on both iPhone and iPad. I’m trying to determine if the issue is an iOS update or something being employed by outside websites.
