With my Apple developer account, i decided to create a wildcard Bundle ID because Apple only allows us to create two certificates and i don’t want to use them for our two main apps, as we want to create other apps soon with different settings. The wildcard ID has an * at the end as required by Apple, as below
This works on my test phone and an ipad. However, one app tester said that the app would install but would not open due to integrity issues (not sure if he followed my steps correctly though).
