This sorry app is a total rip off. Don't ever buy coins. My account was blocked from making an honest comment/review regarding a novel entitle "the temptation of the ex wife" with exorbitant price of 40+ coins per chapter with english grammar so poor that my 6 year old son's grammar is way much better... i am forced to make my review here in google app to inform other possible reader😂. Also, their auto purchase sucks.. they deduct on your purchased coins first and deduct your free coins last
