Can anyone help me find the best way to implement push notifications in China for our situation? We’ve got a camera app and are using Firebase for push notifications. We’re currently in the middle of an unexpected feature in China and have no way of getting in touch with those users! Are there any workarounds that don’t need users to update the app? onesignal looks interesting but they said it does need their SDK installing and the users will need to update and open the app first. (Note- I’ve been meaning to look at other messaging platforms because I’m frustrated with Firebase anyway so I’d like to explore both quick fixes and then the ultimate set up to settle for). I’d be grateful for any suggestions. Thanks, mariska
