I want to use goto and will have about 1800 attending so plan to use webcast. It will be advertised to members of the public so they might use ipads, mobiles or pc's - I wont know in advance. If they join a WEBCAST using a mobile, will they be able to hear/see ok. I read documentation that said it would be fine if they have ior 10.0 or later but then I read somewhere else that it would only work on computers, not mobiles so I'm confused. please help. Thanks
