I’ll cancel the docs call for now in the calendar but you can always put up a doodle poll for availability in the Documentation Working Group Meeting 28th Dec (or possibly Jan 2022!) forum post?
Alternatively the best times for me that work with a reasonable EST timezone are:
08.00am Wednesdays, Thursday and Fridays EST for 1 hr
13.00pm Tuesday & Fridays EST for 1.5 hrs
