GAC Ship Battle Will Not Load

Hello there

I have problems during gac rounds on the fleet part. I am in division 7 and so I have 2 fleets to beat. Each time, I manage to do the first battle, but when I want to do the second, the loading of the game starts and never stops. This happens to me often on rounds 2 and 3, but and this is not all the time the case on the first one. So I am often forced to drop the last fleet which sometimes costs me the victory... 

I was therefore wondering if this was not related to the problem already existing where the improvements made after registration are still taken into account and if other people have already had this problem. 

Thank you in advance 🙂
