When you should or should not dispute a bug
You should only dispute a rejected bug if you are certain that you are correct. Perhaps you did not elaborate enough in your first attempt, and now have additional information for the customer to properly understand the bug. You may use the Discussion Thread to clarify any misunderstandings centered around the scope of the test cycle (do not use the Discussion Thread for difference of opinions on how things should work or post a bug to the discussion thread to request if it is valid or not). If you determine that you need to dispute the bug, please click on your rejected bug and then click the Dispute Rejection button; you will be provided one chance to provide more information to the customer for further review. Be sure to provide further evidence, such as screenshots and video captures (you can upload new attachments after you dispute the bug by clicking on the "Edit" button of the report). This will increase the likelihood of your dispute to be accepted.
One note of caution: Do not overuse this feature. If your bug is a duplicate, out of scope, or not reproducible, it may be rejected completely - even if you dispute it. On the other hand, if you were misunderstood, then you may re-explain concisely (you will have limited space for your dispute explanation). Additionally, never ask the customer to approve your testing work (this includes requesting them to accept as feedback). Testers who violate these rules may be subject to temporary or permanent account suspensions.
Additionally, do not use the Tester Messenger or Dispute feature to negotiate with the customer in any way, In other words, do not ask the customer not to reject your bug or approve it as feedback. We monitor all disputes and tester messenger discussions; testers in violation of this rule will be subject to further review and possible suspension of their accounts.
We recommend that you state the issue clearly and concisely in the first place so that you will not need to dispute a valid bug. And because testers are allotted a limited number of total disputes per month, we advise that you use this feature sparingly and accordingly.
