Hello, We have bought 2 QB for diff companies,1 I can open, work with it, if I'm trying to open Exhibitions(2nd one)it shows like Safary can't open a page

Hi production2,

Are you using the same login credentials for both companies? If so you should see the option to switch company under the Gear icon.

Please try clearing the cache on Safari to check this isn't causing a loading issue - you can see how to on this link.

Thanks!
