When using the premium plugin, the standard Gutenberg "undo" function no longer works properly. This issue does NOT happen when using the Free version of the plugin. If I type some text and press undo when the PREMIUM plugin is enabled, it only removes one letter at a time and then eventually none on repeat clicks of undo, whereas on the FREE plugin the undo functionality works as expected (removes whole word). This means that I can't currently use the premium plugin on a client site, so if you could release a fix soon it would be appreciated.
