Mae'r pandemig yn arbennig wedi amharu ar ein gallu i gasglu peth o'r data rydym yn dibynnu arnynt i fesur cynnydd tuag at rai o'n dangosyddion ac mae wedi achosi rhywfaint o oedi i'r gwaith arfaethedig ar ddiwygio rhai Dangosyddion a datblygu Cerrig Milltir yn dilyn yr ymgynghoriad.
The pandemic in particular has disrupted our ability to collect some of the data we rely upon to measure progress towards some of our Indicators and has caused some delays to the planned work on the revision of some Indicators and development of Milestones following the consultation.
