Yes, with magnets had the same issue. Also happened on my mini tab.
Loctite 480 is your friend. It’s designed for metal/metal including magnets.
Before use - shake very well
During use - use a tiny amount ( don’t get on fingers and then on mod, if you do fine grade steel wool 000 will remove without scratching too much)
After use - store in your fridge
Loctite 480 essential for all vapers with magnets on mods. It’s awesome stuff.
