Virtual office, what are your thoughts?

Back in 2020, we were forced to close our office due to Covid and the many lockdowns that Melbourne had.  We quickly had to mobilised the team of 10 at that time to work from home, fortunately we predominately use M365 and Xplan, with any other software being 100% cloud based, hence no server issues, which made life a little easier.
Later that year we made the decision to give up our office and work virtually. Many advisers said to me that it wouldn't work for them due to their client base being older, they still say it. 
I would like to challenge the thinking around that, we focus on pre and post retirees, who are usually the least tech savvy of any age group, but whilst they like to sometimes see us in person for coffee or lunch, the majority of the work we do is all via video, email and phone, after all they all learnt to facetime their grandkids during covid.
Our business has grown in people, clients and revenue over the past 3.5 years since we have been 100% virtual, yes it's been a lot of work, trial and error, but it can work, if you want it to.
I'd love to hear from others who have gone virtual and what has worked best for you, your team, your business and your clients?
