Thank you.
Yes, the masks did cause a particular problem for those with hearing difficulties.
During lockdown, I stumbled across an online religious service where they had someone signing. This was a volunteer and he's still doing this on a voluntary basis.
Most of the provision that I'm aware of seems to be provided by volunteers.
There was an after-service discussion one time and the volunteer commented that - in his opinion - fewer people are now learning BSL because of a reliance on technology and that this is causing a cultural shift. I've no idea whether there are any figures available for this.
Before I retired, I did work in secondary schools with pupils with hearing difficulties - one pupil had a cochlear implant. The schools are relying more and more on tech, but it's not always reliable. (I retired from my permanent post before lockdown.)
I recall that the pupil with the cochlear implant did have back-up from a teacher who worked with the local hearing-impaired service, but she wasn't always available. She would help by signing during class discussions.
I recall that the pupil's regular English teacher took BSL classes when he realised that there were often problems with the cochlear tech breaking down, but he did this in his own time with no support from the LA.
