On a iPad, the analyze mode is slow

On a iPad, the analyze mode is 'very' slow. If I click the back- or forward button on the PC, the move is instantly. On a iPad, it is slow - you have to wait all the time. If you accidently click a second time within about 1 second, the moves aren't done but the zoom-function starts.
Ok, my PC is faster, but not 100x faster as my iPad. Still, on a PC, it is 100x faster.
I hope a Lichess programmer can fix it :).

You want lichess programmer to give ipad more computing power. Brilliant.

Yeah, it's not really lichess's problem..

Thanks for the informative issue report.

"You want lichess programmer to give ipad more computing power. Brilliant."
I very much doubt the problem is computing power. On the PC, it is 100 times faster. Which PC is 100 times faster than an iPad? Also, what has to be calculated? It's not that I have analyzing on.
Also, the problem that if you click two times (to play two moves back or forward), the zoom function pops up. Which is not needed, and gets in the way. I think this must be a zoom function enabled by Lichess. There isn't a setting to disable it, is there?
