winetou, here's a quote from the notification sent to all BCH holders with Freewallet:
Please use the new address format for sending and receiving your BCH to avoid any transaction issues. Unfortunately, it's not possible to monitor transactions sent to old addresses, so don't be shy and inform us about the payments you're expecting! If someone (or even yourself) made a transaction to your 'old' BCH address, please
contact our support: we'll retrieve the funds for you.
You did submit a ticket to our support team, and we have already started working on your case. However, we cannot be responsible for any loss associated with a drop in the coin value that may take place during that time, and neither are we responsible for the allocation or transfer of any gain associated with the coin value increase.
