Hi

I have had this issue occur a few times,  I currently farm on brutal level 10 using a max champion to upgrade the other three spots.  Normally three attacks on levels is sufficient to upgrade a common 1 star to level 10 ready for upgrading to 2 star.  Usual progression is level 6 after first attack, level 8 on the second and max out on the third attack.

I experience now that it is taking 5 to 6 attacks to get to level 10 with the first attack barely getting to level 4 for a common.  Trying to level up a three star uncommon is excrutiatingly painfully slow process so have stopped trying which is annoying especially with the events currently happening.

I have reset my cache and have closed the game down and resumed several times but this does not fix the issue.

Any suggestions please
