Just to doublecheck if it’s a deliberate behavior or an issue:
I manually add an extension called bypass-paywalls-chrome that does what its name implies.
As it’s obviously not on Chrome Web Store, you need to download it from Github and drag it to Brave’s extensions to install it.
Every time there’s a Brave update, the extension gets removed and I need to install it again.
Maybe its a Chromium built-in security and not specific to Brave, not sure.
Thanks
