A group in South Korea has submitted a paper. Here it is. It would be good to hear from @Leo Ridens and other Physicists here.

My area of research is not superconductivity, but from reading the preprint, it looks convincing, although it will have to undergo strict peer review before acceptance in a journal. There have been many previous reports of room-temperature superconductivity at ambient pressure, but most seemed to have a flaw in the measurements provided. This paper shows not just a drop to 0 resistivity, but also the Meissner effect, which states that a superconductor will not allow a magnetic field to penetrate it while in the superconducting state. You may have seen this demonstrated by something like the following video:

thanks!! but here I thought this was the Meisner effect....
