Cannot update FieldGroup to v4.x

Problem/Motivation

Having just attempted to update the basic FieldGroup module to 4.0.0, I note that the current release of this module blocks us...

 Problem 1
    - Root composer.json requires drupal/field_group ^4.0, found drupal/field_group[dev-4.x, 4.0.0-alpha1, 4.0.0, 4.x-dev] but these were not loaded, likely because it conflicts with another require.
  Problem 2
    - drupal/field_group_label is locked to version 2.0.0 and an update of this package was not requested.
    - drupal/field_group_label 2.0.0 requires drupal/field_group ^3.4 -> found drupal/field_group[dev-3.x, 3.4.0, 3.5.0, 3.6.0, 3.x-dev (alias of dev-3.x)] but it conflicts with your root composer.json require (^4.0).
  Problem 3
    - drupal/popup_field_group is locked to version 1.9.0 and an update of this package was not requested.
    - drupal/popup_field_group 1.9.0 requires drupal/field_group * -> found drupal/field_group[dev-1.x, dev-3.x, dev-4.x, 1.0.0-rc3, ..., 1.x-dev (alias of dev-1.x), 3.0.0-beta1, ..., 3.x-dev (alias of dev-3.x), 4.0.0-alpha1, 4.0.0, 4.x-dev] but these were not loaded, likely because it conflicts with another require.

Can this be update with relative ease?

Thank you
