@M-A-D-A-R-A Few changes that are still required -

1. Profile Screen had a white-colored navbar.
2. Team Details Screen also had a white-colored navbar.
3. The back arrow is not visible in any of the white navbars as they're still white-colored. Change them to a darker gray/black variant as it was before.
4. Add recording for ALL screens. Check the mobile screenshots section in Wiki for reference.
