content: I have been a regular user of the free version for a while and was constantly telling people about this great app. However most of my previously unlocked trees disappeared after the most recent update and it appears this was intentional on the part of the developers. While I understand that this app is part of a business it is very disappointing to have features stripped in this way and it does not motivate me to move to the pro version it just burns the goodwill I had toward this company.
