I think it would be good to block ads that you find offensive / upsetting. I'm normally a premium user (after the free trial, how could I go back!) But need to move the payment date so having to face ads again and just thought that would be a good idea rather than having to quickly alter the volume for ads I or my co-workers find offensive.
We appreciate your patience as we continue to iterate and improve our Free tier. We are working on making ads more personalized to create better experiences for our users. Keep an eye out for improvements, we appreciate your feedback!
