New Blynk connect

Hello. I still use the old Blynk. I’m having trouble switching to a new one due to lack of source code to update BLYNK_AUTH_TOKEN for connections. Therefore, I will not be able to update the data on this device to switch to the new Blynk. Please help, is there any way to log in to the new Blynk server using BLYNK_AUTH_TOKEN of the old Blynk version? If possible, please send any hints to the following e-mail address: Lechkom@onet.pl
Regards.

What do you mean by “lack of source code”?

No, the two systems are totally separate.

The Legacy Auth token and the IoT BLYNK_AUTH_TOKEN perform exactly the same function.

Once you’ve created a template then a device based 9n that template you will have access to the BLYNK_AUTH_TOKEN .
