We run powerbi via the js client library. The client library is great and aren't experiencing any issues with that. We are running into issues only recently where I think microsoft has pushed some changes in the powerbi code that gets downloaded that uses some of the latest javascript features in this specific case the Arrow functions https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions . We run powerbi reports on DOOH devices and some of them are on older versions of webkit. Since a change recently I can see in the logs that the error is because of an Arrow function declaration which isn't supported and is then breaking the powerbi code so the report doesn't show.
I don't suppose there is any solution to this problem. Understand that supporting older version of webkit isn't high on the priority but hoping there is some way forward. Thank you.
Kind Regards,
Daniel
