Got this yesterday while playing ranked PVP on PS4. In the minutes leading up to that, I had also been playing ranked PVP with the batlles processing correctly. After I got this, I closed the app, restarted and did not experience it again that day.
I get this occasionally - maybe a couple times a week over the last couple weeks.
Next time this happens, I will save video and upload it if that will be helpful to you. If so - how much do you want? The 15 minute auto-save on PS4 will take a long time to upload and I don't want to do that if you don't actually need/want that much.
