No write/read information when backing up

[mksa12]

Hello everyone,
I have a question and a problem why it no longer shows me at what speed the backup is being done, specifically read/write

what I mean is that in the past on the previous hardware it showed the percentage and the read/write speed as below

I think LXCs are never showing any progress. That only working for VMs. I think I've read a thread where one of the staff explained why that is not possible for LXCs.
