Sharepoint filtering not working in Chrome as of last week and the response is to that Sharepoint only optimized for IE
At the direction of your help staff we use Chrome as our main browser. As of last week, filtering is not working, and when I spoke with two different support from 365 they told me that Chrome will no longer be supported and that we need to switch to IE, which we continually have problems with...locking up constantly.
As this is missing actual details, we’ll need to close this. There are no details on what filtering this is actually referring to and how it’s not working properly.
Chrome is absolutely supported browser in SharePoint Online and there are no optimizations for IE. This is unfortunately false information which should be corrected.
On the supported browsers in SharePoint Online, please have a look on following article https://support.office.com/en-us/article/which-browsers-work-with-office-online-ad1303e0-a318-47aa-b409-d3a5eb44e452
