You will have undoubtedly noticed the change in the layout to our Ethereum accounts/ Tabs:
​

This allows us to highlight all the tokens you could hold with us.
If you just use us for Ether, don't worry! Ignore those other tokens and just use as normal. 

If you do store a token with us and want to use it, simply tap on the item in the carousel under the account name and the send button will change from ETH (the default) to the relevant Token

Et Voila. You can send a HOT Token.
