Profiles	Equipment		Competence		Network		Routine		Uncertainty
	No	Yes	No	Yes	No	Yes	No	Yes	No	Yes
Low	0.30	0.07	0.23	0.13	0.32	0.05	0.32	0.05	0.25	0.12
Moderate	0.45	0.10	0.34	0.21	0.39	0.16	0.46	0.09	0.30	0.25

Sum	0.80	0.20	0.63	0.37	0.76	0.24	0.82	0.18	0.60	0.40
p-value	0.13		0.96		0.02		0.01		0.21

Note. p-value = Fisher Exact test p-value; Equipment = Insufficient technical equipment; Competence = Insufficient technical competence; Network = Poor network connection; Routine = Difficulties of structuring a digital working day/routine; Uncertainty = Uncertainty about what is the best pedagogical approach.
