iOS app: NextCloud server isnt updating activity on Camera Roll Upload

I just installed the server yesterday, I started the upload of my entire camera roll which is about 23k photos and videos. I saw photos uploading on the activity feed and names of the files. But since accidentally closing the ios app. I have not longer seen any activity on the web site or ios app in Activity. In transfers I see it uploading still the files few at a time right now only videos. Should I be concerned and should I keep the iOs app open because when its not im not sure if it actually is uploading night and Iā€™m still in the 22k range? I have a 20 megabit upload connection with a 300 download.
