I have recently developed a website for a client www.residencefunerairebellavance.com and while the site works well on most devices, he is getting 3-4 calls/day that the site is very slow to load on older models of ipads that have not updated their IOS. It will eventually load but it takes a very long time and many trials. The full menu is not visible at first and when a page loads you only see part of the header. Then all of a sudden, it loads and everything works great?! The clientele is mostly seniors and we simply cannot explain to each of them that their ios version is too old. I am including a video to show the problem and welcome your suggestions to remedy this situation. Thanks!
