Is Safari fully supported as a browser?

[Liams95]

I was just wondering if there are many features missing from the safari experience as I have just noticed that I can't change a new article thumbnail within safari but if I open Sharepoint online in chrome I have this feature. 

So now I'm just wondering is there a lot of features i'm missing by using safari ?

This article is for SharePoint 2016 and 2019 but the browser support is basically the same in SharePoint Online. Note it will also depend on the version of Safari you are using, latest version is recommended.

Yeah I am using the most up to date version, but just keep noticing little things such as a inserting a image into a text section of a page doesn't work either. It just inserts a little broken image box but when I try this in chrome it gives me a box to select my image.

Might be something that needs looking into then as on the page you linked it shows as being supported.
