I have just been running into the same problem: my partner uploaded a .txt file and shared the file with me (two separate documents: one shared directly with me the other one made in a folder we already share). Despite the checkmark being put in, I have no access to the shared attachment. Anything else that could be a possible reason?
Steps to reproduce:
Make a new Document
Make a new node called “Files”
Upload a .txt and link it into the node “Files”
Share the document
Expected behaviour:
When I open the shared document I should be able to access (i. e. open) the .txt file
Actual behaviour:
I get redirected to the browser version of dynalist and the message “Access denied” appears.
