What is the type of the site collection? Whether all site collections occur this issue?
According to the screenshot you provided, when you would like to access a site collection home page, it redirected you to a site collection site contents page.
I have tried to access a site collection home site in the Safari, Chrome and Edge browser on iPhone13, it worked well, directs me to the home page.
First, go to site pages library -> select the correct home page then make it as home page.
Second, access the site collection home page through link likes: https://tenant.sharepoint.com/sites/emilytestnew?moblie=0
