The slack community manager is actually highly active and I also suspect he's not one person but 2 or more guys using one account as you can spot some notable difference in the level of English sometimes. Here in BTT is where support is not that active, but it's not that big of a deal. You can always just go to the slack channel and ask your question there. Community support usually either answers the questions or asks the devs himself on Telegram if I'm not mistaken.
