Ads without warning

This isnt the first app Ive had that tried to blackmail users into paying money to get rid of advertisements and it will suffer the same ignomious fate of being deleted. I understand the developer is trying to make money and I have no issue with that. But the honest way wouldve been to release it as a new app rather than an "update". To retain the forced advertising of the new pay app an "update" that consisted of a new app advertising alert on first launch wouldve been sufficient.

Time to look for another app. Im willing to pay, but it wont be to this unethical developer.
