Yeah, I just set up a catch-all and use individual emails for everything, like the gmail + trick but without sites rejecting + characters occasionally.
Of course, I have several domains and one is a .rodeo that some older sites refuse to believe is a TLD so there’s that problem…
I have one.
I have only ever used the Samsung store to install a single official customisation app that I used once and never again.
As far as I’m concerned it only exists to occasionally annoy me with notifications about apps with updates that I installed from other stores.
