FYI this node is version .20.1 of bitcoin core.
Yeah... you'll see the same warnings in v0.21.
0 as well... but if you upgrade to 0.21.
1, that has the taproot activation code, those warnings will disappear.
As NotATether has mentioned, it's nothing to be concerned about... it's just related to the Taproot signaling... and won't prevent your node from operating properly.
