Google cant sign you in safely inside this app.You can use google sign-in by visisting this app’s website ina browser like safari or chrome

iam using the iphone and Kindly let us know what is the solution ??

Hi @jiniluttumadathil,

Google doesn’t like you using an embedded browser with their OAuth flows. You need to redirect to an approved browser like safari or chrome.

I have tried both safari and Google Chrome browser but same issue
