Enable Push Notification on iOS - Operation Failed

elisawebmail

Hi, i'm new to Reolink. I have purchased an NVR 4k kit.
I can enable Push notifications on iOS if camera is connected via NVR but if i connect without NVR (for example: poe injector and SD card for using Timelapse function) i can't enable push notifications (iOS15.1 on iPhone X) i always get "Operation Failed). Tried to delete camera, delete NVR, reinstall everything, reboot camera, check notification permissions, reboot iPhone, delete and reinstall the app many times, don't know what else to do...my setup is as admin.
Can't solve the problem, push notification is the only thing i can't enable on iOS app. The app version is 4.29.2
Anyone else with these kind of problem?
Thanks in advance for suggestions about this issue
