Having an issue that has just started today out of nowhere
We have dashboards for various things, all working lovely, but if anything (Account/Opportunity/User etc) is opened in a new tab it says URL No Longer Exists. Same tab, works fine.
What I have noticed is the link itself is company.lightning.force.com/s/detail/{accountID}
, which works when opened in the same tab. If opened in a new tab, it goes to company.my.salesforce.com/s/detail/{accountID}
which returns URL No Longer Exists in classic.
Turn Off Salesforce Classic for Your Org switched on in Lightning Experience Transition Assistant, I've also spun up a sandbox to see if the enhanced domains would be an issue, and same in there...
Also thought this might be a browser issue, but I have tried it in Vivaldi in W11, and Firefox in Linux, same thing happens.
No issue in Lists or Reports, just Dashboards using standard objects.
I hope I explainned that okay!
