Cannot start Wappler => “Could not verify user subscription.”

Hello,
I want to try Wappler on my Linux Mint 19.3 machine.
I downloaded latest Wappler version 5.2.2 and after run it want to Login with browser.
I give my email and authorization code but when I want to open Wappler again it show me window with text: “Could not verify user subscription.”
But in my Wappler profile I see that I have active subscription:

So how can I start it?

Try login with your community account instead.

It still doesn’t work:

Ok so now I changed my default browser from Vivaldi to Firefox and
now it works:

Great, so it seems to be related to the used browser. That is good to know, I don’t use Linux but perhaps other users will have the same issue with some specific browsers.

Yes you should write somewhere that you support only some browsers for verify user subscription or check and fix it for various type of browsers (Opera, Vivaldi, Chromium, Brave, etc.) and operating systems.
