Below is the email I've received from Freewallet team:
"Hey!
Asset security and blockchain stability are the key requirements for supporting a coin with Freewallet. Unfortunately, there have been too many issues with the Steem network recently. As a developer, we had to follow this up with additional maintenance on the Steem wallet. During the periods of maintenance, operations with Steem were unavailable, and our users didn't appreciate that.
We aim to provide excellent service to all Freewallet users. That's why we decided to discontinue supporting Steem in Freewallet apps.
Starting on April 1st, 2018:
Steem withdrawals will be disabled;
The Steem wallet will be removed from Google Play and AppStore;
Steem will no longer be available in the list of coins in the Multi Wallet;
Exchanges will be available to external Steem addresses only.
Please withdraw your Steem balance to an external address by 12:00 UTC on April 1st, 2018.
IMPORTANT: We won't be able to stop incoming transactions to Freewallet Steem addresses. However, any Steem deposits coming in after April 1st, 2018 will NOT be monitored or refunded.
If you need more information or assistance with your Steem, please don't hesitate to contact our support team. Thank you for your understanding!
Sincerely yours,
Freewallet Team"
