Whoever decided to start servers for android users, leaving iOS users offline for over 8+ hours, should look for a new, more suitable job. Preferably in business not related to customer service.
Similarly, the one who decided to update the game without knowing the AppStore update procedures.
I have not encountered such a lack of competence among decision-making staff.
Keep it up.

Again, it is Apple fault! Sometimes they just need several hours and you can not know it before. Apple has a process to approve an update, but sometimes you simply receive no response from Apple and you can not do anything.

Dear sir, if you manage a product with 4.5 million users, it is your responsibility to ensure that the update ends within the prescribed time frame. There can be no randomness here. People managing such products should know how to do it. If they don't know, they shouldn't do it.
