Widespread errors, lag, and failed bulk tracking

Switching between programs and tasks repeatedly throws errors that intermittently resolve and then recur, including spurious permission errors claiming actions are not allowed even though they are, which then work and fail again. Student lists fail to load: rosters do not always populate when All Students is selected, and once a roster is loaded under a student group it remains stuck on those students when another group is selected. One teacher reported their tasks disappearing entirely. Bulk tracking is completely nonfunctional and no one can use it. A screen recording of the failures was shared for review. The same behavior has been reported by multiple teachers from different accounts and devices, indicating a widespread problem rather than an isolated one. The situation is time-sensitive because task updates are due urgently, making the broken bulk tracking and loading failures high-impact.
