Siri not working properly

Running iOS 13.5 beta 4 on my iPhone 11pro and Siri is not working properly. Says it is trying to do the command I ask but for the most part it can not complete it. Anyone else experiencing the same behaviour? Opening a Feedback report.

Same here - when on a 4G network both Siri and voice dictation just hangs. No commands are processed. Switch on WiFi and all work fine straight away. I’ve tried all the usual restart, toggle and reset various settings but still no luck. It also affects with similar issue on my Apple Watch which is paired with my phone. Even though my watch has its own data sim I’m presuming as it’s tied to my phone sim in a way, that’s the reason for that failure as well. All other 4G processes work fine - eg web browsing, music streaming
