Why dont you do a bit of searching. You CAN have more than one chime. I have a post in THIS thread that confirms it can be done (I have 3 chimes - the original plus two that I added). I got this info from another user who ALSO posted in THIS tread.
While I have never used the reolink app, it does support pop ups on ios, and i am sure they are working to resolve the issue on android as its mention all over the net. What you are missing is that most folks in this thread are not using it as you would use your ring. They are using this doorbell specifically to integrate with
blue iris. They dont use the alerts via the native popup app and in fact dont want the device exposed to the net. They get their alerts directly via blue iris. This 80 doorbell outperforms 400-500 dollar bells.
