I am unable to understand why a user started receiving the following error message:

"Failed to validate the signature of the actionable message card."

Do you have any suggestions for me?

Thanks

I'm also having this problem. I'm only using the standard approval emails that are built into the approvals action - I have not created any custom approval actions. So far I've only heard of it happening for one approver, but it doesn't happen consistently, and there's no other common denominator. The workaround is for the approver to go to the Power Automate | Action items | Approvals menu and approve from there, and so far that has always worked. But it would be great if the approver could use the emails reliably.

Hi everyone. I believe this was resolved on its own and I never found a root cause or solution. Sorry.

Hi all,

Not sure if this is related but thought I would post just in case.

I was having this issue also but remembered that I had updated one of my flows recently. It seemed that any outstanding approvals before I made the change came up with this message when they tried to approve. Any new / resubmitted approvals worked fine.

I've not had the message since... I apprciate this may not be relevant to people who simply leave their flows alone and this is happening but may help a few.
