Can't comment or like posts in Groups but can make my own posts?

I've recently signed up to Connect in the attempt of being more social. I don't have a Garmin device just yet, but I plan on changing that soon, so I figured I'd get a head start.

However, if I like a post, it immediately is unliked without any input from me. Comments don't seem to work for me either - I'm on Android and I get a message stating "An error has occured".

I can understand if this is a security measure imposed on the device-less, which is fair enough, but I have been able to publish a post in a group -- I'd think that if I couldn't write commentary, I shouldn't be able to make posts either.

Has anyone come across this before, and if so, how did you fix it?
