Ashley This is not true. You can contact Google/Apple support and explain them the issue in proper technical terms.
We already do that routinely. In fact IIRC I've already reported this issue to them. If something isn't getting enough attention, then the more customers who report it to Apple/Google, the higher a priority they will give it. And in this case you don't really need to understand how our engine works. You can just file an issue that says "my game is janky" and they should look in to it.
You can either just complain on the forum and nothing much will happen, or try to do something about it, and it might be fixed. It's up to you! I'm actually trying to help by pointing people in the direction in which things are most likely to get sorted out. If you don't co-operate it makes it less likely to get sorted out.
