expo-permissions is now deprecated — the functionality has been moved to other expo packages that directly use these permissions (e.g. expo-location, expo-camera). The package will be removed in the upcoming releases.

Additional context

Have also downloaded from app store and it does seem to work there - what commit is the app store version associated to?

[josh-gree]

@byCedric FYI - if I use the QR from (https://staging.expo.dev/@bycedrictest/office-marathon - which I found in the logcat output for the app store app it works)

Needs cleaning up some UI nastyness - but it works in terms of permissions etc

• Added ACCESS_BACKGROUND_LOCATION
• Use the two location permission methods Location.requestForegroundPermissionsAsync + Location.requestBackgroundPermissionsAsync

NB: It doesn't actually work anymore with the above changes :-( - This is exactly the issue I have faced in my own development and it is soooo annoying I wish someone from expo could help! The background work now never happens - the app starts the correct permission dialogues come up - settings shows the app has always for location permission - while the app is open there is a push notification saying locations are being collected - as soon as the app is closed the notification goes away - do I need to go back to an older version of the expo sdk? I am using 4.10.1 - this clearly works somehow (since the app store version does) but as it stands I am at my wits end getting background locations to work!
