for the first attempt (marked gray):

Elvis operator always returns the left operand of non-nullable String

for the 2nd attempt (marked yellow):

condition currentUser?.office?.name.toString() is always 'true'

Why is that not possible to be null?

if you call .toString() on a null object, you will end up with a “null” as string and not

null

. You should have

…name?.toString()

Ohhhhh brilliant, thank you my friend 😄 issue fixed

What about when using formatted strings inside the strings.xml? For example, I use the following:

<string name="main_profile_lawyer_title">עו"ד %1$s %2$s</string>

fpTitleTextView.text = getString(R.string.main_profile_lawyer_title,currentUser?.firstName, currentUser?.lastName) ?: "SOME DEFAULT STRING"

The elvis for “SOME DEFAULT STRING” is grayed out.
