Did you really conceive a white screen whilst loading the Mastery Challenges ?
Like myself, I guess that there are a lot of players that play in reduced or no ambiant lighting at all - so did you ever consider our retinas when deciding on a white screen whilst loading the challenges ?
Wholly smoked, your programmers / designers need their eyes examined !!
Or who did I sue for eye damage ?
Hello @movinghearts274 and thanks for contacting Ubisoft support.
I am really sorry to hear that a white screen has a negative impact on your eyes. Could you please provide us with a video so we can have a closer look ?
Thank you in advance.
Hello there @movinghearts274!
I'm sorry to hear that you're having trouble capturing a video on PS4. I've reached out to you in another thread with steps on how to do this, though I'll share the support article on how to record footage on PS4 here as well.
I've shared your feedback regarding the white loading screen experienced when loading into the Mastery Challenges to the dedicated teams for further consideration. If they require any additional information regarding your experience, we'll reach out within this thread.
You also mention that you're experiencing long loading times on PS4. We have an ongoing Megathread for this issue, which recommend checking out when you're next able to. Here, you can share your own report, and we'll also be posting any updates from the ongoing investigation into this issue.
Thanks!
