Summarize your bug EA Support told me to submit the following bug: In the last Grand Arena round my opponent quite fast got 2,121 banners and also had it after clearing the two front zones. When my opponent had cleared the bottom back zone and 2 out of 3 fleets he had the same amount of banners. I fully cleared all four zones while my opponent couldn't clear my fleet zone but still won't without the score even being close.
Steps: How can we find the bug ourselves? See the attached screenshots and the following battle history from swgoh.gg https://swgoh.gg/p/783653643/gac-history/?gac=163&r=3&a=d

From the attack history from swgog.gg it looks like maybe both battles awarded banners. How my opponent managed to have a second battle after winning with the first try I have no clue about.

However - I won the round and didn't get the rewards for that or the improved final rank in that round so hopefully you can help with that.

Let me know if I should provide additional details.
