That is very interesting and quite perplexing I must agree! Well I just got the call from the shop earlier and they were able to witness the mirror shifting position on its own overnight and dropping they are ordering replacement parts they are not sure of the cause yet but hopefully once everything is disassembled I'll be able to supply an update of this grave mystery 😰All i really did was I kept moving it around up down... left to right... i couldn't believe how stiff it is to move and i thought I was going to break it.. so strange but after doing this daily a few times.. i noticed it staying in place better.. I cant explain why but now I nver have to touch it.
