Updating to Android version 449 or iOS version 1.17 (or above) required to open a new bitcoin wallet. Step 1, write your passphrase if you haven't done so already. Step 2, in-app BTC balance will show zero. Your existing BTC will need to be transferred to the new BTC wallet address using https://bip32jp.github.io/english/recovergems.html (type your old passphrase) for the BTC to be displayed by the App.
Your old passphrase will only work in counterwallet. New GetGems passphrase now uses the "default" layout mentioned in the BIP32 spec. (this one time change was needed because counterparty isn't using the default key words to generate their passphrase thus isn't compatible with other apps in the bitcoin ecosystem)
To make things clear:
(1) New GetGems passphrase can be used in https://web.hivewallet.com/ and https://multibit.org/ to recover bitcoins (not gems)
(2) https://counterwallet.coindaddy.io/ can be used for gems on-chain.
(3) in-app Gems are off-chain, meaning they wont show in https://counterwallet.coindaddy.io/.
The update also introduced a major concept change in the GetGems ecosystem. Up until now, each user had to deal with 2 usernames, one GetGems name and one Telegram name. This has caused a huge amount of confusion when searching for users on our platform. Now, your new GetGems username will be the same as Telegram’s so you can search for users easily and quickly. Unfortunately it seems a Telegram user already had your name, you can change your username in the setting tab.
In-app gems were automatically transferred to your new wallet.
Please use https://counterwallet.coindaddy.io/ (its more stable)
