When you open My Account by default it opens to the Library tab.
If you want to show your users a different tab first or a default tab, for example, the Wallet tab, you would need to modify the template My Account layout and add the following code at the beginning of the template.
HTML
<div ng-init="current='wallet'">
This can be applied to any other tab by replacing wallet with the relevant tab name from the My Account common components template.
For example, if you'd like to open the Profile tab for users with Identity Management accounts, you can use this code:
HTML
<div ng-init="current='pianoid'">
