Double checking if the ReactNative version upgrade done lately has affected the performance as it was mentioned in the slack thread multiple times

[PauloGasparSv]

Problem was replicated successfully locally on main and goes to back to normal if tested on a commit before the RN version upgrade. Solving the issue requires a bigger investigation, since this can be worked by internal and external people I'm adding the external label. Also keeping as daily since this may be a big problem that increases qa and test time a lot.
