Since the last ios update on my ipad, no application works (no graphics at all), not even the examples like cargo-bot.
Am I the only one with this problem ?
@Jym What kind of iPad do you have. I’m on an iPad Air with iOS 10.2.1 for awhile and haven’t had any problems at all. Have you tried the usual rebooting the iPad. Or deleting Codea and reloading it.
PS. If you delete Codea, make sure you have your projects backed up somewhere because they’ll be gone.
@dave Thank you for your answer, so if it works with you, I am going to try to delete and reload Codea. I didn’t do it before because I was not sure if I was going to lose my work or not.
@Jym If you delete Codea, you’ll definatly loose your projects. I deleted Codea by mistake once and it took several hours to reload my 300+ projects that I had at that time.
Problem solved. I saved my projects 
and and after deleting Codea and reloading it, everything works perfectly. Thanks.
