In order to ensure full compatibility of Greyd.Suite with the WP core / Gutenberg, we always test each new core update extensively and, if necessary, make adjustments before recommending customers to update. This is necessary, since the core is constantly evolving and changes are not always fully documented.
When a new core version is available, you will find a note in the backend informing you about whether this version has already been tested. There is also a link to the latest supported version.
We highly recommend waiting with any core update until tests have been finished to prevent any problems on your page.
In case you accidentally updated and have problems now, you can always go back to the latest supported version.
