Anyone else use the M365 assessment tool to scan for SharePoint 2013 Workflows?

I used the M365 assessment tool the past several months to scan my SharePoint environment for SharePoint 2013 workflows that need to be retired. Initially it found a few hundred. I scanned again this past week to make sure no new ones have been added and it only found 20, then like 50 the next day when I tried again. I know the workflows are still in the environment. I used the same Azure application authentication method which authenticates fine, no errors from the tool etc. Anyone else run into this and have ideas?
