Hi there, Mohan. We're aware that the GST feature is currently unavailable, and our engineers are working to restore full functionality as soon as possible.
In the meantime, you'll want to log out and back in or try a different supported browser to restore the missing sales tax column. For any previously created transactions, you'll also need to open and re-save them to update the tax amounts.
If the issue persists, you may contact our Live Support team for immediate assistance.
If there's anything I can assist you with, let me know in the comments below.
