Apple recently made it a requirement for us to only display dispensary menus in states with either medical or adult-use cannabis regulations. If your Location Services are turned off then you can no longer see dispensaries. If your Location Services are on and you are in a state without applicable regulations, you will still not see dispensaries. These were the changes they required in order for us to continue utilizing their operating platform and we apologize for the frustration.
For further information on these requirements we'd advise reaching out to iOS support directly.
For Residents of Legal States: Please let us know if you are still having this issue when your location in enabled by reaching out to firstname.lastname@example.org with screenshots of the error message occurring.
