Not quite so. The teams at Canary Wharf are finding the home-based meetings difficult, and not as productive as conventional working. Don't let the on line companies' marketing hype tell you otherwise. There are an awful lot of meetings etc being "pended forward" for when things open up again.
Incidentally, Zoom is seen as for social chit-chat. Canary Wharf finance use the various more mainstream products, which they always have done in such an international business, such as Webex, Teams, etc. Which doesn't stop the BBC etc portraying Zoom as the wonder-all, just republishing what their Marketing department has sent them. This is one of the downsides of the current situation, journalists are not in the office, they just turn round what is sent to them. It's why I am disappointed that BA (both Cityflyer and Mainline) and LCY seem to have zero marketing effort at present, I have seen nothing. Did some unfurloughed, know-nothing bean-counter furlough all the marketing staff ? They should be shouting from the rooftops to all media, front-paging their websites, emailing their contact lists, etc, about start up dates, destinations opening up, you name it.
