Error - Zoho Extension is not available for your region.

Hello Support,

One of our clients is located in UK and they are using Zoho CRM Plus on Zoho.eu. They tried to install our ClientPoint Zoho extension and getting the following error message:- 

"This extension is not available for your region. Please mail us at sales@zohomarketplace.com "  

Can you please look into it and let us know why this issue is occurring for the users located in UK.

Our extension name:  ClientPoint


Thank you,
Gagan Murghai
