Developers obviously don't use this app... A lot of issues such as poor audio recording (even with the doorbell pro 2, delays with viewing who's at the door or who's ringing even with very high speed internet, and a lot more... You will be disappointment... The timeline was very handy, well ....it was cause now it is more likely that you will have to close the app and start it again to see it... No to mention what happens when you try to contact customer service
