Hi everyone,
I’m facing a serious and inconsistent issue with my Facebook Messenger automation and I need help.
My page is 4 years old and connected to ManyChat.
Here are the problems:
• On PC, the “Get Started” button works correctly.
• On Android, when some users click the “Start” button, nothing happens.
• Some users say the bot does not respond at all.
• Some users are receiving an OLD Facebook Instant Reply message that I disabled a long time ago.
• Even though Instant Reply is OFF everywhere, some users still see the old message.
• Users who previously engaged and return after 24 hours do not receive any message.
What I already did:
• Reconnected Facebook permissions multiple times
• Enabled “Take control of conversations”
• Set ManyChat as Primary Receiver in Handover Protocol
• Disabled all Meta Business Suite automations
• Removed Facebook Instant Reply
• Refreshed permissions
• Republished Welcome Message
Still the issue continues.
It feels like Messenger routing is inconsistent or holding old automation memory for some users.
Has anyone experienced this on older pages (4+ years old)?
Is this a Handover Protocol conflict or routing cache issue?
Any expert advice would be highly appreciated 🙏
