Random crashes, bugs, and sync issues over the last few days

So during the last TW, I had multiple issues during battles with a "Sync Error". This was on mobile both on WiFi and mobile, then later on on PC as well on fiber internet. 

Now, I just did a GAC battle with UFU and against Rey, and the whole battle froze where it was and nobody moved. Clock continued to count down and hit 0:00, but didn't end, so clearly another sync issue but no error. I had to Forfeit the battle because nothing happened for 2.5-3 minutes and now I'm likely to lose the GAC because I burned my UFU against Rey and didn't get anything for it. This was also while on the PC client. 

Anyone else experiencing these issues over the last 3-4 days? I've not had any issues like this before, especially across multiple platforms. 

Also, when I exited the PC client, it looked like it did an update? 

From the attached photos, you can basically see that the same situation was active at 2:47 and 0:00. Nothing I did (clicking Auto, going to message chat, changing battle speed, etc.) did anything. It was just hung up.
