Hi I did it, sorry I didn’t notice this post yesterday. If my maths is right then yes there would have been a group open when you posted this. Groups started at 6pm, 7pm and 8pm (UK times). The only restriction being the 15 minute entry window into the Topic group
I don’t know whether the problem you had was at your end or the sites end, there were others in the group at that time though. If the problem persists next week then try and contact the helpline during the day and Harry will be able to help you. Alternatively email the office with details, times you tried to connect etc.
Hopefully speak to you next week.
