We are a bookkeeping firm and have upgraded a number of clients from QB 2018 to QB 2021. Most of them have had issues with the memorized reports - some very complicated reports and some very simple ones. When we discovered this, we reconverted them to QB 2019 which does not seem to have that problem. We don't have time to recreate reports.  Very frustrating. 2021 also runs soooooo slow!
