Don't know about that, but www.bbc.co.uk/news/uk-scotland-60736563 indicates an update due tomorrow and mentions that:
The Office for National Statistics estimated on Friday that Scotland had the highest rate of Covid infections since sampling began in autumn 2020.
One in 18, almost 300,000 people, had Covid in the previous week. The estimated infection levels had risen for six consecutive weeks.
Figures released last Wednesday showed the number of people in Scottish hospitals with Covid was at its highest for 13 months.
So I do wonder if the dropping of remaining restrictions on 21st might be pushed back.
