no issue - followed the migration guide to switch to from lifecycle hooks to single `modify()` method - https://togithub.com/ember-modifier/ember-modifier/blob/master/MIGRATIONS.md - forced resolution of `ember-in-viewport@4.0.2` to avoid older version of `ember-modifier` being pulled in through `ember-infinity`
