We have developed an Excel Add-In. 2-3 weeks ago it was working fine with the online version of excel. We have not made any change but at 28/10/2024 we noticed that the add-in stop working with the error "error installing functions".

@diericd, would you please have a try from your side now? The addin was installed successfully from our side with two different devices.

Hi, there isn't a problem with installing the add-in. The problem is that the add-in's custom functions are not loaded when it is already installed and you REFRESH the page: (this issue only occurs on the web version of excel)

I've just retested and still have this issue.

Thanks!
