Ultimately, the current “Profile” subtab should be the actual “Account” tab. And all the banking stuff that currently sits in the “Account” tab should be a mere subsection above “Help & Support” (which is currently based in the “Profile” subtab).
Regrouping it like that under the “Account” tab makes a lot of sense to me.
Then replace the account icon with a (?) icon and put that on every page. Perhaps in grey rather than pink but this might break UI conventions for actions.
Finally put the “Freetrade” logo centre on every page, right now it’s just on the Portfolio tab. The other tabs look like they are missing something in comparison.
