The text-stroke for desktop devices is displayed ok.
For mobile, the line that cuts the text is not centered.
Any solution for that?
On what device did you test that?
I have checked your website, and it does not look like it on your screenshot.
My device: Moto G6 Play.
I do not have access to Moto G6 Play, but I have checked that on iPhone 12, and Moto G7 Play, and on both of these devices, it works correctly.
Please, clear your device browser cache, and check if the problem persists.
