Hi @Ryan23 , As I was about to download the Acr app i was scrolling around and just looking at some of the other one's and the reviews on them and happened to come across the Cube Call Recorder Acr by Catalina Group and read nothing but great reviews so I downloaded it and it works absolutely great no problems what so ever with my note 8 Just thought I'd share that with you all. Once again thank you for your help Ryan I appreciate it.
Hi Guys ACR sent out versions yesterday to try and all seems ok at the moment.
You can enable WiFi call recording in the app but this has always been temperamental, the same thing your find until all the bugs are fixed or adjusted Bluetooth connections.
It does look all positive now as most app developers have found a fix.
