In your opinion, what does it mean?
Maybe all InspireTheme will be updated another time?
Rockettheme and InspireTheme are two different companies.
Rockettheme update their templates and we update our templates.
What Matias means is that Rockettheme will update their templates to address this issue
, not to make them Joomla 4 compatible.
The "incompatible units" issue is present only in our Lawyer template. For more details, please have a look at this discussion
If you are waiting for us to release the Joomla 4 version of our templates - it will happen at the end of November or the beginning of December.
Regarding your second question - how do you know that next week their will be another Gantry 5 version?
Matias said that next week he will release a script for updating the deprecated SCSS, not a new Gantry 5 version.
Anyway, you can update to Gantry 5.5.1, it is pretty stable now. Or just wait for Gantry 5.5.2. There is no rush at all.
