Gaps between coping and tiles

[Florida_Man]

Hi guys first time pool owners here. The pool was resurfaced 4 years ago and we moved in last year.
I have noticed there’s a small gaps between the coping and the tiles. The actual space between the tiles and coping is small but it goes around most of the pool.
Is this something that needs fixing asap? How would it best be repaired.
Thanks

Depends where your pool expansion joint is and if you have cantilevered coping…
