Are they mutually exclusive, though? You might think the tools are adequate - or even good -, but not be happy with how other people handle remote collaboration.

My experience has been, that some people really like to call you directly and expect you to take their call, without creating a meeting or asking you if/when you have time. Others (still) have problems with muting/unmuting themselves or realizing that everybody can hear their environment. And I think when you're accustomed to never or very rarely working from home, there are a lot of things you have to do differently, so the learning or adaption curve is kinda steep at the beginning.

I would respond similarly for my own work situation. We're using Microsoft Teams which is fine and in many ways a big improvement over the hodgepodge of tools we used before remote work en masse was considered viable by my employer. Still, it has changed the dynamic and that is a challenge as it affects individuals differently. Some colleagues have become more communicative, others less so, some want to use the phone more now, others are happy to use channels to post a stream of what they're working on without addressing anyone in particular, etc.

What that says to me is, the tools and processes are fine. Getting people to use them is the challenge.

That's essentially how we interpreted it as well. Tools are still important, and useful in the right context, but we're in a period now where tools are not hindering remote proliferation.
