Hey, magenta4793591! I tried to walk through these steps to understand better where you're bumping into trouble. I get to this section:
and I click the blue link that says +Add Custom Greeting.
Then I get this pop-up:
and so I click Choose File.
I don't actually have any MP3 files on my work laptop, so I had to stop there -- but can I ask, once you select an MP3 file from your computer/laptop, are you not seeing the magenta Save button in the bottom right corner? Or do you click it, but then nothing happens?
Lastly, do you have the ticket number you received? While we aren't able to file or escalate tickets from this public user forum, we can check status so I'm happy to take a look at that for you if you like!
Marissa posted some awesome steps and screenshot. Can you take a peek and see if that helps you out? Thanks!
same here, magenta button is not active, it does nothing when you click on it
Oh dear! That's certainly no good! Have you tried using the Visual Voicemail app to set up your greeting? Open the app, click the 3 dots in the upper right hand corner, then select Settings. The first option here is your greeting. (For example, mine says "Default") Tapping here will take you to a list of available greetings. To record a new one, tap the microphone in the upper right hand corner. Once finished, tap the greeting to add a check mark and set as the primary greeting. Hope this helps!
