Hi Bill,
Thanks for reaching out. I have experienced the same thing. There are a few alternative plugins available here: https://marketing.adobe.com/resources/help/en_US/dtm/c_dtm_switch_plugins.html. Another option is to manually enable debugging using the console:
Enable/Disable Staging
localStorage.setItem(‘sdsat_stagingLibrary’, true);
localStorage.setItem(‘sdsat_stagingLibrary’, false);
Enable/Disable Debugging
_satellite.setDebug(true);
_satellite.setDebug(false);
There is a cheat sheet available with more commands on Jim Gordon's blog here: http://jimalytics.com/tag-management/dynamic-tag-manager-dtm-cheat-sheet/
Let me know if that doesn't work.
Best,
Tacia
