Hi, this is probably the wrong place to ask this, but I'm at my wit's end.

I upgraded yesterday to Trados Studio 2021 and my workload has increased tremendously as a result. This is mainly because the update broke my QA checker rules that had been working just fine previously. See here and here. Now when I'm checking over translations, I'm getting HUNDREDS of completely unnecessary false positives, which I can't possibly check through. As a result, incorrect translations can potentially slip through, affecting my company's quality and ultimately my job! 

I expected better from SDL, especially considering that some of these issues such as broken grouped search expressions have already been fixed.

I know it said during the upgrade process that the upgrade is irreversible, but I wanted to ask anyway. Is it AT ALL POSSIBLE to switch back to the previous version of Trados Studio?
