TLDR:

Set app:hintEnabled="false" for TextInputLayout

Description:

If you leave hintEnabled to true (true by default) the hint will be single line and turns into a label when the user taps the EditText giving it focus.

If you change hintEnabled to false this feature is removed and the EditText shows the hint with multiple lines as intended. It does not turn into a label and disappears once the user starts actually typing.

<com.google.android.material.textfield.TextInputLayout
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    app:hintEnabled="false"
                    app:boxBackgroundMode="none">

                    <com.google.android.material.textfield.TextInputEditText
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:hint="Your long hint"/>
                </com.google.android.material.textfield.TextInputLayout>
