1sat is 1000msats; a 1sat payment does not trigger any issues with msats on any wallet I've ever seen, and I don't see how it could.

The problem isn't the wallets but that many LNURL providers don't support msats but round to sats or throw an error. So anything below 1 sat will indeed get rejected. Examples are Alby, WoS or LNbits (even phoenixd doesn't support msats for their REST API). And lightning addresses are very popular for receiving.

If you run your own LN node yes, it should be just fine to receive it. But I've seen many stackers here using WoS or other custodial shit wallets that will reject under 1 sat.
