This has been an issue since my first install of Hyper EU for Houji since 24.3.18, not sure if it's been reported.
1. Swipe left from home to Google Discover
2. Open a link with Chrome (disabled open in app)
3. Swipe up to go home
There is no animation and user will be returned to the Discover screen but the first few user touch and swipe will interact with main home screen.
This is shown by the app drawer being open behind after I swipe up the first few time after returned to Discover.
