Hi @peterpme - we’ll need some more specific information in order to help you with this issue. What URL are you trying to pass into canOpenURL? Could you provide a snack that minimally reproduces this issue?
The reason iOS returns false is because the googlegmail scheme isn’t whitelisted in the Expo client. Some apps used to probe for well-known URL schemes to figure out what you have installed on your phone, which was too much of a privacy issue under Apple’s judgement.
