My complaint:
Dear Rovio, please help me to claim my clan battle rewards as soon as possible. Around 2pm this afternoon, I pressed the collect button on the clan battle to claim my rewards. But it suddenly encountered connection issue displaying Please check your internet connection, so I pressed the back button. I retried to open the clan battle, unfortunately collect button already disappeared and it says Event completed. I cannot claim my rewards anymore.. I do not have the photo of connection error but I have screen shot of the clan battle with unclaimed reward saying event already completed
Suggested solution:
AB2 must fix the bugs of sudden disappearance of claim reward buttons if encounter connection issue.
