I use shortcuts to document libraries/views in SharePoint on my taskbar in Windows10. This is very convenient for quick access to your most used libraries.
However, to keep them all apart I've changed the SharePoint icon that Edge displays by default (the same for all libraries) to custom icons. this has served me well for about a year or so (although its really awkward how this is implemented in Edge).
But, now the last couple of days something weird has started. Some of these custom icons are being replaced by SharePoint icons, and their position on the taskbar moves (from somewhere in the middle out to the right hand side). Even stranger is that the SharePoint icon that my custom icons are being replaced with differ from one another.
See pic below..
What could possibly cause this weird behavior?
