Not seeing signagures

[Jeremy180]

I have not seen signatures in quite some time including my own, despite unchecking the "collapse signatures" option in my preferences.
Is this due to signatures not being supported on mobile devices?
(I have only logged in on my phone within the least year)

You can’t see signatures on mobile phone, unless you use “landscape” by flipping it sideways.

Thank you, I suspected that to be the case, but it's good to get confirmation.
