Hi @AllanLusui
Thank you for the detailed post, and welcome back to the community!
Were you able to resolve the issue?
Please see @YuryR’s suggestion for a similar issue, here: “Requested dashboard not found issue version 2.33.8 - #6 by YuryR.
I’d emphasize the point (Make sure that the cache is cleaned before the user accesses the dashboard: (1. Data Administration - Maintenance - reload apps, clear application cache, 2. Cache cleaner, 3. Clear Browser Data).)
I hope that works. If the issue persists, could you get more info as mentioned here.
Thanks!
