So yea, after 10 hours of funds being “on hold”, I reached out to wallet support. This is what I got from them.
Thank you for waiting. 
Your deposit has been put on hold because our systems flagged it as a high risk incoming transaction and cryptocurrency cannot be credited to the bot's wallet.
Please provide the external BTC wallet address to which we can return the funds.
Pretty much the same response as what OP got. So coinjoined sats are high risk and not ok to be sent to Telegram bitcoin wallet, even if it’s only a small amount. Not to mention using legacy addresses and fully custodial. This wallet’s so called bitcoin support is simply horrible.
