On 7/8 - one of our numbers in the plan (iPhone 😎 got added to a random text group made up of numbers not in the contact list! Today (7/9) an unknown number got added to our text group automatically (this was a nexus ) and one more phone in our plan (iphone) got added to another random text group!!
What is happening? Are others experiencing this kind of random additions to unknown groups? I saw some folks reporting this issue on ATT and Verizon in late 2017. I called Tmobile support today - they denied any widespread issue and did not create a case for my issue !
