Lab data, as well as online analysis tools show my site to have 0 cumulative layout shift (CLS) issues in mobile and desktop versions. However, Google field data is showing 0.30 CLS issues, (Critical, no passing level!).
Is this to be expected and typical? I have no other ideas on how to fix this. I wonder how people can still experience CLS.... perhaps they are on older devices that don't respond to modern code, therefore having CLS issues?
