I have noticed that since the last update that the notifications on my iphone 6 are not working right. Today I got a message that I defeated the Kraken. Went into the game and it was actually a merchant ship. More annoyingly I get notices that my tavern is full while I am still recruiting pirates. I think it happens when I use the rehire button after a successful attack and then later use the rehire button after donating guild ship crew. The timer for the notification seems to stick with the original rehire crew. So I am still recruiting 10 gunners when I log in after receiving the message.
I noticed some weird things too. Biggest one I have seen is not always getting notified when my island was attacked...
