For that glorious online support it’s best to update it as soon as possible.
The change-log did not contain much, but here goes:
Improvements Included in Version 5.0.2 (Distributed 4/16/2018)
General system stability improvements to enhance the user’s experience, including:
- Resolved an issue that caused motion controls to respond incorrectly when playing games that use the feature
- Resolved an issue that caused user icons for recommended friends to not display correctly
That stability is all I need and a glass of wine.
With these updates, there is often hidden gems. If you find any let us know in them comments por favor.
