I am extremely disappointed with Dropppin. It seems that the project has been abandoned, which now causes our own connected project to no longer function. We invested a lot of time and resources into integrating with Dropppin, only to now find out that support and development have been completely discontinued. It is incredibly frustrating that we now have to look for an alternative solution because Dropppin failed to fulfill its commitments. This situation could have been avoided if there had been clear communication about the status of the project. I cannot recommend Dropppin at all.
Lesson learned. Never depend on amateur projects.
