After a recent update of Sydney Pro theme, the original font on my website (i.e. Arial type) has been changed to the present font style as display on: https://www.o2s.group/
I have checked with the server host provider and they tired restoring to an earlier (a week ago) yet the present font is still showing.
In addition, some icons/symbols (e.g. social media platforms at the page bottom) and elsewhere on the website cannot be displayed. Only empty squares showing.
