Today Golconda Vja to SC 30% empty 600 avl against 1800 in booking for ticket of Rs 125. So you can see the demand is. Regarding corona AP is in better placed in taking precautions then Hyd they take data and check the traveller health and take swab and covid tests after 7 days and advise quarantine but I dont see any care in metros. Anyway buses may start next week between AP TS.
