+Some apps operate under the assumption that no more than 4 attachments can be returned or uploaded. Pleroma however does not enforce any limits on attachment count neither when returning the status object nor when posting.
+
+### Limitations
+
+Pleroma does not process remote images and therefore cannot include fields such as `meta` and `blurhash`. It does not support focal points or aspect ratios. The frontend is expected to handle it.
+
 ## Accounts
 
 The `id` parameter can also be the `nickname` of the user. This only works in these endpoints, not the deeper nested ones for following etc.
