I have seen repeated reports & questions regarding buttons not sending / quick replies not working - going as far back as 1y ago. No Manychat support provided other than some vague “reset your permissions” or send link without buttons (not great of you are trying to get emails in platform and have advanced automations with follow ups).

Does anyone actually have a plausible explanation and suggested fix? I personally suspect the devices playing a role as Iphone seems to have the most success. 

Given that Android is far more common globally, you’d think this ranks a bit higher in terms of finding a solution?
