Occasionally, after typing in my password, the sign-in box isn't enabled.
No matter how many times I tap it nothing happens (you can also see that it hasn't changed colour).
This happens on at least 2 of my Android devices (Pixel C, Galaxy S2) and possibly also on my Nexus 7 (2013). Various versions of Android (including the latest on the Pixel).
It happened with the old app and with the recent replacement and it happens after I have confirmed that I've got a good, fast network (and internet) connection.
Restarting the app (tried up to around 5 times) makes no difference, but if I try again later in the day everything is fine.
This sometimes happens when I'm at home (i.e. connected to the same network as the PC I'm trying to access), but I can't remember if it has happened elsewhere. When this has happened at home, I can ping the PC.
Am I missing something obvious here?
