On my desktop (on my phone it isn’t showing up at all I figure it just takes time). This is problematic because you have to download a photo before deciding whether to delete it.
To be specific the full dimensions are not shown, it is cropped more square and it is lower quality and pixelated.
No the photo is rectangular. That said I seem to have found a workaround that is obvious is retrospect, opening photos through my Icedrive folder in file explorer (which opens them in the usual Windows photos viewer)
