It’s a good practice for QA to check on production issues. They will get to learn the gaps that could have possibly led the bug to leak through the QA gates.
However, such issues occur mostly due to environment mismatch. A small tweak in registry setting, resetting browser cache or restarting the backend service fixes the problem.
By lending support to production, QA can expect to find out untested areas and add them in their test plan. So it’s a worth the exercise which will ensure quality in the long term.
