When I click "Add to cart", the portal immediately shows:
"Failed to add phone number to cart"
The telephony cart remains empty ($0.00, no items), and this happens for all available numbers.
This issue started only after I deleted/released my previous ACS phone number.
Before that, purchasing a phone number worked normally.
