Emails disappeared

I need help for the following problem
I AM NOT ABLE TO SEND AN EMAIL EVEN IF THE WIDGET IS IN MY DASHBOARD
1)I am using arduino nano IOT33 ( I selected MKR1000 Wifi in the dashboard)
2) Blynk i s working correct but the emails
3) Initialization ==> Blynk.begin(auth, ssid, pass);
4) I communicate with ARDUINO with an android app developed by myself and all works fine
5) At the beginning the emails were sent but now I cannot see them anymore

What shall I check ?
Emails are sent to gmail.com

I add the part of code responsible for email sendind

String body =(String(“Mi sono svegliato ora. Buona giornata”)+"
");
String body1 = " Tensione Batteria : " +String(t1,1)+"
";
String body2= " Temperatura Locale : " +String(t,1)+"
";
String body3= " Umidità aria : “+String(bH)+” %"+"
";
String body4= " Umidità terreno : "+String(Ground_Hum);
body=body+body1+body2+body3+body4;
Blynk.email(“xyz@gmail.com”,“Subject: Nuova Partenza”, body);

What library version are you using?

Pete.

Thanks for the reply
library is
1.0.0.-beta.3
downloaded directly from the skecth menu
I add a doubt (not sure of that)
I recently used arduino agent software (now uninstalled) . Can it be a problem?

Yes, uninstall the beta version and install 0.6.1

Pete.

Great PeteKnight !!!
It works finally

TWO THINGS I MADE
1)I changed library from beta to 0.6.1
2)and put in RUN Mode the project on the dashboard . Before it was not in RUN because I supposed that not ncessary because I use my android app to communicate with arduino
