Description
Ticket: CP-8525
There seems to be an issue with async calls such as setTimeout, promise,...after upgrading to RN 0.73.x which slows down the app on Android. From my investigation, this has to do with event loop implementation in Android JSC. It looks like this might already be fixed in RN 0.74.x (with new arch and bridgeless mode enabled) but we are unable to upgrade right now since some packages such as react-native-quick-crypto, react-native-pager-view are not compatible yet.
As a workaround, I'm replacing the promise polyfill that RN uses (https://github.com/then/promise) with es6-promise. This prevents the app from freezing.
