I have a classic experience SharePoint site, but I have created a new modern home page which works fine on browser and Android App. But for some reason on iOS SharePoint app it goes directly to the activity page instead of the home page by default (as show in the screen shot).
I have to advise all users to go to the sharePoint site, and then click on Home to see the home page.
I created a new test sharepoint site (modern experience) and it goes directly to the home page fine. I'd like to explore any options in the old site that I could change instead of moving to a new modern site.
I have also tried creating a modern page and set it as home page, but iOS app still defaults to Activity whilst Android app goes directly to the home page.
