Mobile compatibility is theme-dependent.
Looking at your site, you are using
mai-law-pro theme — a commercial theme.
Since you are using a commercial theme and need support, please go to their official support channel. In order to be good stewards of the WordPress community, and encourage innovation and progress, we feel it’s important to direct people to those official locations.
Forum volunteers are also not given access to commercial products, so they would not know why your commercial theme or plugin is not working properly. This is one other reason why volunteers forward you to the commercial product’s vendors. The vendors are responsible for supporting their commercial product.
Thank you so much @t-p ! That actually helps greatly.
