Yes, definitely not using the beta version.
I put together a system on my own server to keep track of the last ping received from EventSub websockets and report any that are considered “dangling”. So far, the two that have been reported are:

Dangling for: 1149s
The dangling time is the time between the last received WebSocket message and the time the subscriptions were forcefully cleared, despite their state.
I will add more as more are detected.
