UPDATE - 4:45 PMThe government has issued an update via the Aarogya Setu Twitter handle that stated the issue had been fixed and registrations were back on, around half an hour after the issues were first spotted. Calling it a “minor glitch” the Twitter handle has stated that registrations for users above the age of 18 are back on track. Missing OTPs, inability to load the website, Aarogya Setu app crashes, these are some of the few issues mentioned by users on Twitter while trying to register on the government's portal. We were able to access the CoWIN website ourselves, but the Aarogya Setu app appears to have an issue with registration, at least when it comes to new users. The government later issued an update via the Aarogya Setu Twitter handle that stated the issue had been fixed and registrations were back on, around half an hour after the issues were first spotted.
