I was trying to register my name in app store connect, I was trying to use few names and it said they are already taken, hence I have went ahead with a new name and it was available. So I have almost finished my development . Today I have again searched app store with my app name to make sure there are no apps. But there is an app in exact same name. If it was already available? Why did apple allowed me to use that name and showed it as available? The only reason I could think of is, either their bundle ID or SKU Is different between mine and other app in store. But when i search for the same name now, I can see that app, Will apple allow accept mine ? Or should I change the name of my app?

I have an app in store which has in app subscription, while checking for renewal it is not providing me exact end date of subscription based on which I have to lock / unlock certain features. It never fetch right date to verify, this is seriously a little thing which seems to be too complicated.
