hi, Tank_Liu. did you resolve the issue?

if (@available(iOS 15.0, *)) {        [self.tableView setSectionHeaderTopPadding:0.0f];      } helped me to resolve the issue, thank you lmDeveloper1

Hi guys, we're also facing the same error with device running under ios 14.5, in a managed app (User Enrollment flow). in unmanaged app device token is generated as expected.
