Grafana Dashboards Access via IPhone Bowser

Version: 8.1.1
OS: self hosted Debian

Guys, i am facing the problem: I cant access grafana dasboards by using IPhone browser. I have tried to read the tutorials and issues but i could not get the clear picture, why its happening. 6 months ago it was not a problem.
should i update the grafana?
If i update, is it safe? because we have our customers.

Thank you
