Storyline 3 bad performance on older iPad and tablets

Hi, 

I have been doing some testing using older iPads (mini and 2) and noticed that the performance of SL3 output is completely unusable compared to Storyline 2.

The animations are slow, the page transitions are slow and there is constant intermittent crashing. It even caused the iPad mini to restart. 

The Storyline 2 output, while quite slow, still works and you can complete the course.

This puts me in a really difficult position. In an ideal world, clients and users would have the latest technology, but this is not a reality. You do not change your tablets as frequently as you change your phone.

Clients, as you know, have hugely diverse employment and our courses have to work for as close to everyone as possible.

I cannot say to the client that the SL3 output works on iPad. It is as simple as that. If I stick with Storyline 2, which looks like the ONLY option to keep the courses working on as much as possible, I have to admit that it does not work on Firefox without Flash (this issue was never rectified in 3 years).

It is hugely frustrating as a developer to constantly have these issues due to no fault of my own. I am really disappointed in SL3's lack of new features and now the output. 

Does anyone have any practical ideas that they have used to successfully combat these issues? Mobile player is not an option for our SCORM courses.

Many thanks
