I wanted to offer a little update. The issue is resolved on Android devices through a new update. (You will to manually download it from the Google Play store)
The players effected on both platforms are (to my understanding) completely random. I'm still trying to receive further information, but I have heard from many Apple players that they are able to play today even though nothing has actually changed on the platform just yet.
To be clear, the reason why there is a new update on Android and not iOS yet is that Apple requires that we submit updates to them that they then need to review and accept before we can release the update. This process fluctuates in the amount of time it takes depending fully on how many submissions Apple is capable of reviewing in a single day.
I'm extremely happy to hear that many of you are back up and running, but for those of you who are not, keep an eye on updates from your device's app store.
Thank you all for your patience and understanding.
