Services is not defined in Beta

Thunderbird Beta
#1 
ChromeUtils.import("resource://gre/modules/Services.jsm");

I have this line of code and so does Owl for Exchange and it is creating errors saying “Services is not defined” in the Error console for both Owl for Exchange and my own addon.
What has changed and how can it be fixed? This is in TB 67.0b1
I asked for help for this and then saw that there was this option in the Beta page. Not sure which is better. Feel free to delete one of them.

Services is not defined
#2

This seems to be a problem as well in getting anything from managed storage.

Thisdomain = await browser.storage.managed.get(“domain”);

This doesn’t seem to work and suddenly I have the error message
Services.policies is undefined
Services.policies is not used in my code.
