The system has been incorectly DND ing messages for a long time. 3 major ways
  1. The wrong messages... Today someone sent me a đź‘Ť and GHL marked the person DND
  2. Yesterday I manually removed a random tag and it DND the contact and said the contact opted for it but they did not
  3. in the past I have manually turned on a single DND channel and it DND on all channels. Then I have to remove all DND, THEN I go back to add the one channel DND it it will work
MAJOR MAJOR problems here. This has been broken for a long time and seems to be getting worse. If not worse then it is at the least a continued problem.
