Here is a research topic for you.
When does requesting a subscription wipe out other subscriptions you had requested?
This is the new if then else I wrote before, so you can run only one way at time.
This isn't the best way or the right way but I hope it works.
As @ABG and I said to you the best way is to make only one call and then manage the data.
I hope the hint of ABG will give you a new way to do
Good night
