Hi here and welcome
You cannot go back versions sorry as its all web based, so its not really installed as such to go back. But we have other options to get this resolved.
What exactly happens when it does not work? Please let me know.
Can you hold the home and power buttons on your iPad for about 10 seconds until you see the Apple Logo, then release.
Let the iPad restart and when it has, tell me if the app now opens please.
Sorry it was not clear, did you do the last instructions I gave? Just need to check.
Can you press and hold on the Photon app until it wiggles and you see an X
Press on the X to remove it
Then repeat the initial instructions I had you do
Then go to the App Store and download and install the app again and tell me if it now functions please.
ok, then they introduce an incompatibility with the iPad 1's.
We have one last thing to try else we need to look at other methods for you to play these games.
We will reset the iPad. This will remove all data from it and return it to new, but you cannot avoid this, so backup any data from it first please.
Then go to Settings, General, Reset, Erase all content and reset settings.
Let this complete and when it has, setup the iPAd again like when you first received it and tell me if it then works please.
ok, then its not compatible anymore, it is getting more and more like this with the iPad 1, such as youtube not working ect.
I am really sorry but unless they bring out an update for this, you will not be able to get around this.
Though have you tried to find the games you play on facebook, within the app store? As a lot of them exist there.
ok, via the iPad 1 it wont be possible on facebook anymore with Photon so we try another app,
Download and install Mercury Web Browser and try to use this with Facebook.
Let me know how you go please.
