Questions about Thunkable

Hi there,
My account has been upgraded to thunkable Pro. However, I can not create a new variable. I only find the variables that I have created before my account be upgraded. Could you help me please to know how can I create a new variable?

Now you need to initialize variables you can’t create them (it’s basically the same)
