Gmail is giving me an error message when trying to send the log to your support (some security issue, not related to size). What's the "share link" you mentioned?In addition, could you please generate and download a log report in TOS > Technical Support > Report Issues, then send to our support mailbox for analysis? If the system report is too large to be sent by e-mail, you can delete the /etc/tos section of the zip file, or you can provide it to us via the share link.
