I’m particularly fond of the design choice to activate childlock if you press the cancel button twice, which results in every public microwave at my uni getting locked accidentally on a regular basis. Handy for me cause I know how to unlock them so theres always some free ones

that likely means your instance hasn’t federated with lemm.ee or has it blocked, check the block list and if its not blocked search the text “[email protected]” in your community search, it will show not found but if you leave it a second to index it and try again it should work
