epic power up does not work any more on one board

Question

Hi,

we are using the epic power up since many months.

yesterday it stopped working.

when clicking 'add to epic' the drop down stays completely empty. In the java-scipt console I see the following:

index.js:1 you are using a legacy api key "e2b***********28c7", please re-authorize the power-up
jquery.js:5508 Error while parsing the 'sandbox' attribute: 'allow-storage-access-by-user-activation' is an invalid sandbox flag.

background:
- it's working on other boards

- we have a story-board that references epics on a (different) epics board.

Does anybody have any idea?

I solved the issue back then, by archiving some epics.

Same here but with other power ups:

Error while parsing the 'sandbox' attribute: 'allow-storage-access-by-user-activation' is an invalid sandbox flag.
