Inappropriate ads

Is anyone else getting wildly inappropriate ads on Duolingo? The condom has been coming up frequently and today I saw the one about abortions and whether to divorce your husband or beg him to stay if he's cheated! I thought this was an all ages educational app and was considering getting the family membership but I'm not having my kids see this kind of advertising. It's disturbing and disappointing. Suggestions for alternative language apps would be much appreciated!
