Galaxy Watch not charging on new triple charger

[Jenniferoleary2]

I recently got the Samsung triple charger (EP-P6300) to charger my phone, ear buds, and watch. It works great for my phone and ear buds but it is not charging the watch. It has a specific section made for the watch but when I put it on, it just blinks red and doesn't charge. Any idea what is going on? I have searched online and can't find a solution.

I always clean the base of the watch now, my chargers the same usually red light blinks so I know to clean the back sensor & sometimes to need to move your watch around abit so it hits the right place

It seems that the new wirless chargers are not supporting the original galaxy watch - at least it is not on the compatibilty list (only Galaxy Watch3, Watch Active2, Watch Active). What a shame.
