My suggestion is to contact their support team, unless you are willing to experiment yourself with real coins.
Are they offering active support somewhere? They have different social media channels like reddit, Discord, and GitHub. That's probably the best way. Their Telegram channel is only for announcements - no support there. I don't remember if there was a live chat option back when I tested the wallet briefly. Another option is to get in touch with the Horizontal Systems team.
I don't know which support is the most active, but the option to contact via twitter DM, or on Discord so far is usually always active.
Or send some questions or complaints via email.
Too bad that they forgot the most important part - swaps between Tron and Tron-based tokens and other cryptocurrencies. It's questionable whether or not it will be added in the future.
For Tron exchange support is not yet integrated, but exchanges for other tokens on several networks such as ERC20, BEP20, POLYGON, ARBITRUM, OPTIMISM etc.
are already available integrations with DEX 1Inch, Uniswap, Pancakeswap etc.
and in the future, Unstoppable Swallow will also complete integration with DEX Thorchain which allows for decentralized exchange between asset types such as BTC, ETH, LTC, ZEC, BCH, BNB, ERC20, and BEP20.
It seems that there will be many updates in the future, perhaps the addition of
BRIDGE will be needed as well.
Send your request to the developers to integrate the DEX Exchange for Tron assets, the more requests, the faster it will be integrated.
