Hi All Hope this is the right place for this question. Has anyone else’s ‘Record ID’ format changed recently? Ours has been 6-digits for a long time, but suddenly recently it’s jumped to 10-digits. Obviously this doesn’t make any operational difference, but I was wondering if anyone knew why the change? Thanks all Robin ---

Ah, cool, thanks! Only started effectively in March, that’s why I only just noticed.
