100MB is too large for those.
Even with a paid account
I saw your second comment just after posting mine. I think a subscription removes the limits. I use satellite.earth 165 sats per GB.
I bought a couple of GB and currently only using 178MB so my storage is paid through 2027 at the moment. I only use it for files too large to attach to notes.
