The GET method is not supported for this route. Supported methods: POST. Error only occurs on mobile but works fine on PC?

I am getting this particular error that only exists on mobile..
The idea of this function is that the user can convert one risk to another type of risk. The get method will get the ID of the first type of risk, then the target register.
Then the post will convert this risk into another type of risk.
This works fine on PC. However, on mobile I get this error and I just can’t make sense of it.

Below is my routes.

And this is the error I am getting.

Can anyone help me understand why this error only occurs on mobile yet works perfectly on PC?
I’d expect it to work fine on both.
