New arcade - Does it accept add-ons?

Uploaded my game to the new arcade but all I get is a white screen.

The game is quite large in size and contains an add-on behaviour. Are these allowed? Is there a size limitation? It uploaded fine and I can play other games, but I just get a white screen for mine.

It even appears to disables some of the built in plugins such as Webstorage and Browser.

But third party addons should be supported: : All third party plugins supported!

...Remember it is in beta.

Just report any issues in the relevant section - https://www.scirra.com/forum/new-arcade-beta_t129648 - as requested by Tom.

One of my games doesn't even have addons, but it looks like other people have been able to play them, since they've been played and rated. Also, I can hear the music, but I just get a white screen. So it looks like they do work, but I simply can't see them on my screen (though I can see games that other people have submitted).
