Seeing a strange bug with a members-only page. The initial navigation to the page requires a sign in. On the page, there are two repeaters hooked up to data collections; the repeaters are empty, as this error crops up:
Failed to load initial data Error: The current user does not have permissions to read on the X collection.
Where "X" would be the respective collection names. If one refreshes the page, this issue completely disappears and the repeaters are populated as expected (this persists through the duration of the user's session).
The collections' read permissions are set for site members, and all other permissions are admin.
