Lost changes in Qlik Sense September 2020 Entreprise Patch 5

[Eli]

Dear Team,

I Lost all my changes done today on my dashboard after refreshing the page the dashboard is showing the latest change from yesterday. All changes done today are gone.

 The expressions and master items used are heavy (include several if conditions ) and they are taking time to be evaluated . I don't know if this could affect saving the changes on the server.

Please Let me know what could be the problem because we faced the same issue in previous Qlik Versions and they told us that it will be solved in the newest version and still we are facing the same problem. 

Appreciate your help in this case.

Thanks.
