Blynk notify compile warning no working notify

Hardware Adruino nano 33 iot, using wifi
blynk beta 3 library
android app version 2.27.28

so I can connect and get notification when device disconnects and reconnects. but I cannot in my code notification. I assume the compile error only thing holding me back. My virtualwrite works as it should so I know everything else is good. harware im simply jumping pin 3 and 5 to get output/input to later put in relay.

compile error i get is this…

Are you part of the beta testing programme?

If not then you should un-install the beta library and install 0.6.1 instead.


ok ill try that no i am not part of that.

Ok update problem solved. that was too easy thanks so much.
