Why is it that I can use the marking function on my mobile phone without any problem, but I can't use the marking, measurement and other functions on my tablet

Hello, Sir. When I use it on my mobile phone, functions such as measurement and marking can be achieved. However, the same content cannot be used on a tablet. After clicking the marking button, the expected marking does not appear on the drawing. Of course, there is no error report on the console either

Humm... tablet has never been tested actually, and I'm not sure what's the difference between tablet and mobile. Theoretically, it should work for any browser. But we didn't test against many browsers, chorme, edge, firefox, safri, etc. should work fine.
