Before the update i was able to make a filter just for the loggedinuser but now i'm getting this error is there any way for filtering a record that allow the logged in user to see just te info requested by himself.

Can you describe what you're trying to do? The source filter is used only when syncing the data, so the reason functions like now() and loggedInUser() are not supported is that those functions aren't likely to be relevant (e.g. there's no loggedInUser() to assign during the sync).
Assuming you'd like to set the record to only be visible to the user who requested it, then like Stefan said you can either use security rules (if in 22.1 or later with synced records) or Default Filters (if using non-synced records or prior to 22.1).
