Google Pay is one of the shittiest apps in India.
The GPay app doesn't show all transactions. I saw this bug in 2021, and to date, they haven't fixed it. Despite its big name, this experience is below third class. The GPay team is so shameless that they never fixed the app, even though some of their competitors have a very good experience.
For example, if you use PhonePe, they show all transactions. If a transaction is in progress, it will show as failed or succeeded later. GPay doesn't even show transactions like this.
