So I managed to make a purchase and sync the algorithms to my H9.

 

To those who come across the same issue, follow these steps:

 

1) In the paypal window, right click and select properties.

2) Copy the URL of the page

3) Paste the URL into a new browser window.

4) Complete PayPal transaction

5) In the H9 Control, in Settings, click on Restore Purchases.

 

After this, the new algorithms are available in your H9 control. 

 

Eventide: please look into this. I think the issue is that the H9 Control app is using InternetExplorer11 by default on Windows 10. I added the paypal page as favorite and was only managed to access it from IE11. I tried disabling IE11 in the features, but that didn’t do anything.

 

So I still can’t make purchases inside the app.
