Apple Watch side button stuck
One day after my workout my 2-year-old SE went crazy- the shutdown prompt would appear over and over after I tapped 'Cancel'. The side button felt OK, but was clearly stuck down. I tried other solutions posted here- using water, and/or soap to try and free it to no avail. Finally I tried spraying a small amount of WD-40 on a cotton swab and and rubbed it over the button. It immediately started working normally! Thought I would share this here.
