Hello, we're noticing that the methods "_('Message').translate()" and "_.isPhoneDevice()" are not supported anymore in SC 2020.2 (We got our SC updated to 2020.2.3 today). Is there any documentation for this? We have been using them in our extensions since a while now.

We had same issue and used Utils.whateverfunction() directly. Prior versions added Utils to an underscore mixin which was handy.

Utility functions are no longer mixed in to Underscore, so you will need to use Utils instead for things like 

isPhoneDevice

.

Thanks Steve, will do that.
