Why do I have to reload metamask every time I open a different site

I’ve finally overcome the issue of not being able to connect to Metamask (by removing phantom wallet etc) but now the issue is that everytime I move between sites (even if I’ve been connect 2seconds before and flicked between sites) that utilize Metamask I have to re-sign in. Metamask should be able to remain open for the time I have chosen within the Metamask settings as it does with Chrome. Also, it’s having issues connecting to the Ethereum chain so, once again, I just go back to using Chrome. This is very frustrating since the MM issue stopped me using Brave for over a year in the first place and do want to support it. Any ideas?.. I’m using MacBook Air 2020 M1 and OS Venture 13.3.1
