Lichess Bugs me Out

Me and my friend play each other on lichess but every time we play moves are made that my I friend and I didn't do.

If you have any problems similar to this please reply, or if you have any problems/bugs with lichess that seem weird or anything else please reply.

Anyone?

I noticed this a couple years ago, when I would send a link to my friends to play. It was a glitch that would let spectators make moves. I don't know if this is the same problem.

It might be.
