GJC Web Design, as I understand your extension is not jet ready for J4,so I will use native Joomla reviews till then.
I know loot of people here in forum tell me not o migrate jet, but reason for me to migrate is because I get warning about indexing page because of mobile view, I could repair J3 css, but J4 is out a years now and one time we will need to go there.
