Hello 3CX Team, I am facing an issue on the Android version of the 3CX app. The Quick Replies / Canned Responses icon is not showing in 3CX Chat on my Android mobile. Because of this, I am unable to use the quick reply feature, which is very important for my work. The same option appears correctly on the desktop/web version, but it is missing on Android. Please check this issue and provide an update or fix in the next release. Thank you.

Pretty good app. I like just about everything. The only thing that is keeping me from giving it 5 stars is that when you receive a call then hang up your notifications still show an incoming call. It's not ringing or anything, it just shows like it is. It doesn't impact functionality, it's just annoying.

Very intrusive, little options. Trying to use this when I work from home, but when I'm in the office near my desk phone there's no way to turn it off. Even when I force stop it sometimes calls will still come through. Also the interface is NOT user friendly at all. You can't even see a list of internal numbers when transferring calls, better know them by heart! Edit 2/25/25: The developers comment below is false. I changed it to silent, still causes my watch to vibrate and show up on my phone.

Worked perfectly until this morning. Now I am getting the following message: Update required. Your server version is too old to connect to via app. Please contact your administrator. UPDATE: My system administrator says they have updated to v20. But I have no way of knowing if this is true, other than my app still not working.
