We are aware that 2013 iPads (like the iPad Mini 2 and the original iPad Air) don’t have enough grunt/memory to run Wordchain inside a browser. It appears to load fine in Safari, and then when you enter a chain it completely reloads, which is very frustrating. Apple discontinued these models in 2017, and since 2019 has only offered security updates to iOS 12.5.5 (the highest iOS these iPads support – as of July 2022, the latest iOS for newer iPads is 15.6)
It is possible that some older Chromebook and even 2014 iPads may struggle too.
As one teacher noted: “We realised the devices were older than the kids using them.”
