Chápu, že Tesla fanboys jsou náštvaní.
Ale to, že teď Mark Rober a JerryRigEverything vydali video nemá vliv, že díky Muskovému chování padají akcie poslední 3měsíce.

#GA4 update IRL.
I can see the percentages from the column in GA4 now too. Compared to the "GA4 Fixer" plugin, the difference here is that the number is on the same line and not below the number itself.
