A bit like 1-2 months ago when 5.2 or 5.1 was first released, all of my custom GPT using Actions that call a webhook towards Make Integomat stopped working.
1-2 months ago, the call to the connector would appear but no “Confirm” or “Deny” button would appear.
Today, all my Custom GPT started saying that they used the action, but no call to the connector are made. When I switch to Legacy Model 4o, than the call is indeed made to the connector.
