I have been collecting ivouchers to open the next chapter and instead of allowing me to open the next chapter the app automatically opens a chapter ahead so then I have to wait to collect more ivouchers so that I can open the correct chapter it has happened more than 3 times and I'm getting fed up with it bc the chapters aren't cheap either and I have to wait an entire day or 2 to be able to open at least 2 chapters if this keeps happening I will just have to uninstall this app for good
