Useless lag doesn't go away – BF Mini Wiki Review

The moment I start the app it leads me straight into an ad with nothing but white background. There's no 'close' button anywhere and I can't get out of it in any way. Useless ad with white background always pops up the very second I start the app. Please fix this.
