Thanks @Sanjeev @peopleinside for your answer. We installed the lastest version yesterday. To Try descart db issues i made a clean instalation to reproduce and y get the same issue.
@fripoll you are welcome. Are you sure that is not a browser issue? Tryed with incognito, other browser etc?
I use the laster version and I don't see this issue so maybe will be interesting understand how reproduce with PHP or server components version.
You may also check if you are able to reproduce in the demo: https://demo.uvdesk.com/
Have you also checked server error logs?
Thanks @peopleinside and @Sanjeev. I made lots of tests and y could reproduce the issue in the demo. I made a new agent with administrator role, asign some tickets, login with de new agent acount and in "my tickets" section can see that there are tickets but are no listed and it show "no record found"
Note: there is not problem with "agent" role. Only "Administrator"
@fripoll Are you able to do a small GIF and to share it?
Please be sure no personal or sensible data are present.
For made a free GIF you can use an open source software like this one: https://www.screentogif.com/
When you activate the demo and you choose to login in the admin side you are admin and if I create a ticket this one is visible from admin side so I don't know how to reproduce.
When you create an agent there are different permission you can set so the issue can be related to those permission but on administrator profile I'm unable to reproduce. I never tested on agent side.
Oky @peopleinside i made a small .gif video about 1mb but i cant upload here because of this error 
anyway the issue is very simple to reproduce. Tickets assigned to agents that has "Administrator" role are not listed in "my tickets" view like show @Alessandro-Gabba in the first post "26 mar 2021". Tickets asigned to agents with "Agent" role are listed correctly. Thanks a lot!
