Wake on wrist raise not working on Apple Watch SE

Hey, guys.

Today I went to the pool with my wife and decided to keep my watch on. It was working perfectly inside the water. We stayed there for close to two hours inside the water.

Got home, everything still working.

Went on to use my watch tonight and the wake on wrist raise is not working. It’s toggled on, the theatre mode is off.

Have I damaged my watch without knowing?

Any ideia how to resolve this?
