Issue Summary:
From 00:00 AM PDT on Saturday, June 24th, 2023 to Monday, June 26th, 2023 10:18 AM PDT, some users on the desktop and browser apps encountered a 'failed to send' error message when trying to send messages with files attached.

The issue was caused by a recent change to how file permissions are read when files are shared. This change was reverted, which resolved the problem for impacted users.

Our team is making efforts to prevent issues like this from reoccurring in the future. Thank you for your patience while we sorted out this issue.
