where are they looking?
script execution logs on script/script deployments are time filtered, if you want to see older logs you have to go into the script log view page itself?
also there's a cap on # of logs, if you've got a script that's logging 10,000s of logs and its running very frequently you may be hitting that cap
I guess confirm admin and junior dev role are looking at the same THING but SEEING something different as a step 1.
I'm not aware of any permission that filters logs, pretty sure its all or nothing.
