Hello,

does anyone have issues with loading the calling extension? Iframe window is very small (set to 200px width and height) and settings, which are set through the setting endpoint are not taken into account. Used endpoint is [https://api.hubapi.com/crm/v3/extensions/calling/appId/settings](https://api.hubapi.com/crm/v3/extensions/calling/appId/settings) and width and height are set here as 400 and 620.

Another issue is that click-to-call (onDialNumber event) is not triggered when I try to start a call.

Both issues worked fine on Friday, but without any changes on our side just stopped working today? Any ideas? Version of

@hubspot/calling-extensions-sdk is 0.6.3.

See attached screenshot:

Thanks in advance.

Having the same problem, I’ve noticed that if I am completely clear the cache it works fine, and then breaks again.

Iframe not loading at all, and if I click the icon of calling app, its loading but onDial still not working.

The same is for us. What makes it really weird is that our solution is already built months ago and it was working fine. Yesterday, just stopped working without any changes on our side, so I thought that there is some kind of an incident on HubSpot’s side, but still cannot find any information.
