I'm not able to reproduce this with adblock. Can you try disabling individual lists and let me know which one appears to be the culprit? I can then investigate the list source directly.

@benw-pusher Thanks for the suggestion. I tried as suggested and it turns out it’s not the filter lists that blocked the Pusher SDK.

Turns out, it’s the Distraction Control feature available to AdBlock Premium (which costs $2/mo). I think this feature recently rolled out. I did not remember enabling it, so I guess it may be enabled by default for paying customers.

Since it is a paid feature, I also opened a support ticket to AdBlock side and will update when I hear back.

Thanks @dtinth . I suspect this is not something that AdBlock will change, as that would be circumventing the purpose of distraction control.
One workaround for this could be to self serve the files, hosting them on your domain instead of a Pusher domain and potentially preventing the block - however I can't guarantee this is a solution as I'm not certain how the distraction control works.

Yes, you are right, received this response from AdBlock:

Thank you for your patience.

After consideration, the Distraction Control team has opted to continue blocking Pusher as it uses push notifications.

We may have to self host it then. Thanks for the suggestion 🙏
