The bug has been fixed then reintroduced a total of 3 times now. What gives?
I play through Google Play Store on Android with a Samsung Galaxy Tab 3. I do not have score boards either. Season 9 scores came up after the last update, but I could not access it. Then, when Com Arms was supposed to come up, I lost everything. Now I don’t even see the scoreboards at all.
Edit… score boards are now wrking. Thanks to D3 for fixing this. 
I actually emailed support about the missing post-event summaries. The response was that it was only really fixed for events that started after the R68 patch. I’m not entirely sure if Combined Arms started before or after the patch was out, but I figured I’d see what happens with the current PvP and email them back if I still don’t have a post-event summary.
ETA: I have my summary for Earth’s Mightiest so it looks like this is indeed fixed.
