Clear cache, free up to 900MB(here I specify with a large margin, so you may need less) of disk space so that Google can use it to run the game, reboot the device.
If it stucks at 90% again, wait a little longer without letting the device go to sleep. Another option is to reset the download, reload the page and restart the game (I find it strange, but it helps sometimes).
Also there will be an update on the 19th, so the situation may change.
Нope my recommendations help. Stay tuned!
