I'm not certain.
Take Gmail as an example: they unilaterally decided to discontinue support for admin-set signatures on their iPhone app, without any prior announcement.
Here's the relevant support thread: https://support.google.com/mail/thread/232355527?hl=en
I believe there's an underlying issue at play: Google engineering and management seems to overlook the impact that abrupt changes like this have on businesses that depend on their services.
If google cancelled either of those I'd be very surprised and equally disappointed.
