Sorry for the late response. I was not able to find any information about why the input focus is not triggering on iPad. I recall that a few months back I was researching something similar, regarding the virtual keyboard. The conclusion was that IOS does no longer allow programatical triggering of the virtual keyboard – at least that was their last response at that time. They usually change it every now and then.
Maybe, this is something related to that as well. Even if the input gets focused, there is a very high chance that the virtual keyboard will not open, simply because it's not allowed to do via triggered events, only via direct touch. You could try this modification, but I'm not sure if it will do anything:Best,
