I’m running the website on an iPad with 14.7.1 software. I’m not getting that notice in safari. Very strange. I do seem to remember starting to get that notice on my iPhone a number of months ago with other websites I frequently visited and realized that Apple upped their internet security protocol requirements. I needed to change my ISP to wp2 or something like that (one with higher encryption) and it went away on that device. I may be getting the acronyms wrong, since I am basically a functional illiterate with these types of things.
although not directly on point, I quickly found this with a web search - https://forums.att.com/convers...a51a72a09d3b07501c40
setting mine to wp2 only fixed everything.
