If you just created a new SuperGroup and want to access the SuperGroup Vault/Bank, you need to do something first before you can start depositing credits, opening new tabs (for a total of 8 tabs), etc.
Start by setting the credit deposit/withdraw limit for any RANK. It doesn't have to be a firm setting, as you can always change it later.
However, NOW you have access to ADD CREDITS to the Vault. This is very important, as you need to do this before you can start to unlock the tabs. Each tab costs 10 N. So, putting even 1 G of credits into the deposit is enough to start.
Select the BUY tab and start buying/unlocking tabs. You can have up to 8 total tabs for the SuperGroup Vault/Bank.
Full disclosure: long time player and it has been a looong time since I created a new SuperGroup. I have done this occasionally, mainly for diversity and STORAGE.
