Issue with Superchart

Hello! I am trying to add datastreams to the the superchart on the Mobile Dashboard and it seems like the “+” sign becomes unavailable after adding 2 Datastreams. In the documentation it states that up to 4 Datastreams can be added. Is it something I am doing wrong? My datastreams are Virtual pins with double values if this does have an impact on the subject.
How can I add more datastreams?
Thank you in advance!

According to the website, you are limited to one datastream only if you have the basic (free) subscription.

What subscription plan do you have?

Okay. I understand. I have the free subscription. Thank you!

I also have another question. Where can I see a balance of the energy that I have used?

Blynk IoT doesn’t use energy.

Pete.

Great! Thank you!
