Have there been unannounced changes to RNG aspects of Ultimate Team?

In the past week or so it seems like some of the random chance aspects of CUT have changed dramatically. By random chance aspects I mean things like linemen losing their blocks very quickly or missing them entirely, receivers catching contested throws or ones where they're hit immediately after the catch, defenders dropping easy interceptions, etc. The most obvious difference has been fumbles which have increased significantly, even when holding the button to "Protect Ball".

Momentum/Composure seems like it might be playing a larger role as well. Once a team gets "hot" or "cold" their RNG chances change drastically, moreso than in previous months.

Have there been any recent changes that would impact the RNG aspects? If so, is a changelog available?
