Hi Anshuman
Thank you for your email.
Sometimes it occurs. When I refresh it twice, the error goes away.
The new sign-up features has sign-ups with mobile number as mandatory. That is a good approach to avoid bots and mis-usage.
Constructive feedback:
What if a startup has 5 concepts and each concept needs to be built on separate GitHub accounts? Before the signups via GitHub did not require a mandatory mobile device SMS confirmation as verification. It would help startups who needs to build their GitHub repositories and segregate them accordingly instead of compiling all their repos of all concepts under one account.
This is just an opinion.

Bfinity.
