@martijnpoppen Thanks for this app, very useful.  
The only thing is, sometimes messages are not send (or received?). I only send to one phone number. Used in multiple flows, but missed messages are not trackable to a specific flow. All flows are hit and miss.  
Any idea what could cause this behaviour?
