Identity requests Approval for every transaction after cookie expires

I originally posted this in /frontend, but it was the wrong place. We're having an issue on Safari desktop with approvalRequired on the React web app we're building. I understand that Identity needs to request access again 1 week after login, but we are finding that even after approval is given, and the cookie is updated, Identity continues to request access for **every** transaction thereafter. i.e.:

Given that I'm using Safari
And I logged in 1 week ago with access level 4
When I attempt to buy a coin
Identity requires me to Approve transaction
And when I Approve transaction, then it is successful
But when I attempt another transaction
Then Identity asks for approval again
Despite the fact that the seed-hex-key in Cookies was correctly updated to last another week (i.e. now to expire 2 weeks from when I originally logged in)

We'd appreciate if you could look into this or provide some insight.
