I think I've mentioned this before, but I can't find it. If I reply at the first level and I don't include the “address” that is not included at the first reply level, then the account on Mastodon does not receive a notification. The post arrives, only the recipient does not receive a notification.
This is probably an incorrect interpretation of Mastodon. If I include the address, there is a notification. I've gotten into the habit of always entering the address. It's annoying, but doable. Not for people who switch from Mastodon, though. (Translated by a machine from German)
