my vodacom app - multiple phone numbers

[droplet]

until recently in the my vodacom app, i have been able to check the balances for both my wife's and my phone numbers. my contract is the primary one, with my wife's number being billed on my account.

i was always able to click on my phone number and it would drop down to show both numbers and i could select hers. no more. is this a change in the app, or did something change when my wife got a new contract and phone a month or two ago?
