Hey Azza2! Our teams are hard at work trialing a potential fix, and an update has been pushed to the Google Play Store, it will roll out shortly.
We'll need your help to confirm if it has worked as expected, so we will keep you updated as the release is pushed out. We wanted to give you the heads up that you'll need to update the app once the release is live and let us know if you're still seeing the issue.
We'll keep users updated on my broader announcement post here: 👀 Can't sign in? We're looking into it! | MYOB Community
