Guys, I have a question, I'm making a game for WebGL. Does it handle WebGl touch correctly from a phone?

Question

C++ / C#

Or there are some pitfalls. Why am I asking, if you play on the site through a PC everything works fine. But if you play through the phone on the site, then it turns out that in one click the character manages to apply the jump force several times. I fixed it and made a switch to ios to check through the phone before uploading to the site. And it also works well on the phone, but when uploaded to the site, the problem remained.
Here is the touch verification code

if(Input.touchCount > 0 && _isGround )
        {
            Touch touch = Input.GetTouch(0);

            switch(touch.phase)
            {                
                case TouchPhase.Began:                
                    Jump();
                    break;              
                case TouchPhase.Moved:                   
                    break;
                case TouchPhase.Ended:                 
                    break;
            }
        }

Answer 1

Suddenly, someone will collide, did a reload of the jump and it all worked)
