As title reads I've been looking for a workaround about this issue, but neither these forums or reddit have it (or at least I didn't find any solution). The problem is simple:
I have a Collection from Sharepoint with entries that might have or not Attachments, after collecting the table into PowerApps and using that for another gallery (to pick what entry I want) I've tried everything but nothing works, the new gallery (based on what's selected on the first one) doesn't have the property '{Attachments}'
The first gallery 'GCCD_AvailableTraining' is filled using:
Sort(Filter(GlobalTrainingRepositoryCollection; Or( 'Headline competency'.Value = GCC_Competency.Selected.Competency; 'Subcompetency 1'.Value = GCC_Competency.Selected.Competency; 'Subcompetency 2'.Value = GCC_Competency.Selected.Competency)); 'Training name')
The second one 'GTR_TrainingMaterials' should display attachments:
GCCD_AvailableTraining.Selected.'{Attachments}'But '{Attachments}' appears like this:

And that's false because the selected item, in this case for example, has the property '{Has attachments}' and even the value its true:

And before asking, I've tried all the posible capitalizations and nothing appears. While I am writting this in english I am using PowerApps in Spanish what has been a problem before, because for example I cannot use 'Office365User...' but 'UsuariosdeOffice365' , but it doesn't seem like a problem of that type (because i've tried using spanish but nothing pops up).
I must say that in sharepoint I was unable to find attachments neither in the collection itself on sharepoint (but I did find 'has attachments' in powerapps. Any ideas?
