Shared access to project on Local Blynk Server

Hi! I have installed and configured Local Blynk Server following instructions on your github page. It works pretty well, but i cant use a shared access. I powered on shared access in mobile application blynk, but when i am trying to scan qr-code, blynk says that the project is stopped by author and i cant use project. Whats wrong?

Study the docs again as QR is covered.

Read the docs twice and let us know if you still can’t use QR codes.

NOTE: Your Project should be active, don’t forget to press Play button.

Thanks, now it is working!
Also i have a question: can i configure the frequency of reading virtual pins in WidgetHistoryGraph on Local Blynk Server?

Didn’t get your question.

Value of virtual pin was set to 0 at 00:00, and at 10:00 i opened the app and it was increased. But according to a plot on the picture, at 00:00 the value of virtual pin was not 0. So the WidgetHistoryGraph updates the plot only when app is running? Or i did not get the principe of WidgetHistoryGraph right? What can i do to have a normal plot? Thank you for your help.
