I still can't trade my holdings in Europe, not that I would like to sell, but I see value of EMH as 0 EUR.

First they chaged ISIN from VGG3191T1021 to AU000000EMH5, but then another change was made to AU0000332975. If I would like to buy EMH, I can do that with placing order for AU000000EMH5, but my holdings are kept under AU0000332975 and I can't trade them.

I contacted broker and this is their answer:
The new ISIN is not tradable. Therefore, no price/value is displayed.According to the information available to us, the ISIN AU0000332975 is only a placeholder and the ISIN AU0000332975 should be derecognized and a new ISIN should be entered shortly afterwards.This is likely to be ISIN AU000000EMH5 again. However, we still have to await receipt of the new shares from the depository. As soon as these are available, they will be booked into your securities account as quickly as possible.

It's this way for about two weeks now.
