Cant connect arduino uno wifi rev 2(Mega 4809) to Blynk

Hi guys,
I am a beginner with arduino and blynk
Im using arduino uno wifi rev2(mega 4809), arduino IDE 1.8.16, Blynk app2.0 version 1.3.4
As it is stated in many topics that to use arduino MKR1010 examples for arduino uno wifi rev2 now when i am using this example my ide with library version1.0.1 is giving error that it cant compile for rev2 and when i downgrade my library to 0.6.1 the program is getting compiled but it is showing invalid token in serial monitor.
I dont understand what to do now it feels like a great problem.
Please help me solve this problem and also tell me how can i upload my sketch and error code as iam totally new to this community
Please help me at the ealiest
Thank you

You can’t use Blynk library version 0.6.1 with Blynk IoT.

Have you tried updating your WiFiNINA library?

Pete.

also suggest an alternative way to connect my arduino to blynk via wifi
i also tried wifi provisioning using edgent example and it gives out errors

@ZAID I’ve merged your second post into your original one.
Please don’t create multiple posts about the same subject, it gets very messy when people start replying in multiple locations.

I’d suggest that you read my response to your original post.

Pete.

Im sorry actually i am really tensed about ths project

@PeteKnight i have the latest WiFiNINA library version 1.8.13

Your code is missing the Template ID, and this needs to be the first line of your sketch.

Pete.

@PeteKnight i have added it and still im getting same error and im using arduino web editor as i have messed up my libraries for my arduino IDE

@ZAID you are using blynk IOT right ?

@IoTDude where you able to upload it to arduino uno wifi rev2?

@John93 yes im using blynk IoT which the new one not the old blynk legacy

@ZAID if you continue to post questions about the same issue in multiple topics then your forum account will be suspended.

Please consider this to be your last warning about this.

Pete.

@ZAID first Add BLYNK_TEMPLATE_ID and BLYNK_DEVICE_NAME on top of your firmware, above any includes.

Second please listen to Pete advice.

@PeteKnight im just trying to find answers
i didnt realize the confusion this would cause.
i wont repeat it

@John93 is this the correct way??

i am getting the same error

How did you get the auth token ?

@John93 i took it from the blynk dashboard

Yes that’s right, now everything should work just fine.

@John93 it is not compiling

@ZAID I’m gonna try something and I will let you know.
