Webview preview for non pro apps?

today i check’d some experiments i’m used to work far from the real app ,
those are non pro accounts , in the past webview used to work in the editor,
now its not,
i’m on Brave and Big Sur Mac M1 .
Is it only me ?
Do i have to go pro even to preview if Webview is operative now ?
I’m also worried cause my pro app in using iframes with webview…don’t tell me my work is not going to work ( while still does for now ),please.

Still works for me to preview in the builder.

Thanks for your answer.
Are you pro?
Maybe its Brave…going to try with Safari… .
Yes its Brave…really curious behaviour.
Have a good Sunday.

No, it’s on a free app.
