Everytime time I open a trello board I get 'sandbox' attribute error

[Ricardo Machado]

Everytime I open a trello boards I get the error 'sandbox' attribute: 'allow-storage-access-by-user-activation'

This happens to me in the latest version of the following browsers

-Edge

-Chrome

-Firefox

This causes a big delay before being able to use trello searchbox.

Does anyone knows a solution for this?

Thank you

Did you get this solved? I have the same error and I think it's related to not getting the plantuml app working (my issue is described  here https://community.atlassian.com/t5/Confluence-questions/plantuml-app-diagram-always-shows-broken-icon-on-page/qaq-p/1432529 )
