Yes, this kind of inconsistent access to the Messenger microphone icon (when acting as a Page) has been reported by others. Based on what you’ve shared, it does sound like a permissions or access-level issue tied to the client’s specific setup, not the Page itself.
Here’s a breakdown of what’s likely happening and what to try:
Possible Reasons & Fixes:
1. Check the client’s Page role in Business Settings
Even if they have access to the Page, their role might be limited (like Analyst or custom access), which can affect functionality like sending voice messages.
What to do:
Go to business.facebook.com → Business Settings → People
Click the client’s name and confirm:
If not, upgrade their access temporarily to Full Control or standard Admin role and test again.
2. Make sure they’re using the correct app context
Sometimes Meta Business Suite opens Messenger as themselves, not as the Page, even when it looks like Page mode.
What to do:
3. Try on a different device or re-install the app
There could be a local device glitch or outdated app version.
What to try:
Sometimes just doing a clean app install resets things.
4. Test with Facebook Lite (for Android users)
Some users have reported the microphone shows up in Facebook Lite, even when it’s missing in the full app. Worth a try if you’re troubleshooting.
Bonus Tip: Try assigning the client as a test user in another Page to isolate the issue
This helps confirm whether it’s their account permissions or something Page-specific. If the mic works on another Page, it’s a Page-level permissions thing. If not — it’s user/account/device-related.
If all else fails...
Use Meta Support Chat (via Business Help) and raise it as a Messenger functionality bug tied to the user account. Mention that the same Page works fine for others, but not for this user.
