iOS 12 beta iMessage problems

hi I have 4 iphone X and 3 macbbok pros and 1 Ipad pro all on my account ,, i have updated 2 phones and ipad to beta and i have tried taking all the other devices off my account in hopes it can help my imessage issue, all works great until messaging then from either of the beta phones they can work when messaging a SMS phone not another iphone i have lost one number or contact -just GONE !! then i can only text one other number on my account no matter what , example I type "tay" a message and it will switch to "xander" when sent is pushed and "xander" recieves the message because he was last one that WORKED! i have done almost every reboot i can find is the something im missing thank you in advance

I have the exact same problem with different names... LOL... I have posted in bug reporter, but this has been an issue since beta 2... now on Beta 6 and still not resolved. I have even tried using new apple IDs across devices and it is still the same problem. Hoping they resolve it in beta 7! This is terrible!
