Hmm, I know that there are probably settings that work just for mobile, but I would have to do some digging in the documentation. Let me see what I can find.
Thanks Jennilee. I like Toggler much better than Mouseover, and it works with Grid. Unfortunately still does not work with IOS/Android. Screen taps do not map to clicks.
Can you copy and paste some of the code you're working with? Maybe there are areas you could trim down the code to make it more efficient.
I haven't done much with the Wolfram cloud myself, but I do have a few remarks:
You don't need Mathematica Online for Cloud Credits, you get a few of those with your (free) Wolfram account. I'm guessing you already have one since you're able to deploy to the cloud at all. Is it possible that you just forgot to set Permissions -> "Public" for your deployed objects? That's necessary if you want others to view your content, and public objects should not cause a login prompt.
Permissions -> "Public"
Everything gets sent to the Wolfram Cloud servers and then back to you, so anything from a slow connection to a low priority on the server can slow down your computations. You can always try to make your code as fast as possible on your own machine and then hope it'll be faster remotely as well...
I suspect that anything purely browser-based will work in a lot of different browsers, or if it doesn't, it's probably worth a bug report. If you need to deploy a stand-alone app, then I have no idea what the limitations may be, sorry.
