I looked for some type of setting on my IPad related to opening links but did not find any setting. Are item 1&2 possibly using the same "mobile" CSS? I had no issue when my site was using Joomla 3.10.x. I did verify the calendar event open behavior on an test site running Joomla 3 and the calendar event opens with a click on the IPhone Safari browser.
