Hanging / pending behavior for update mutation

What is the current behavior?

When I do command --> await mutate(), sometimes it will just hanged and not finish, especially when I do update mutation. The strange part is that the update mutation is actually success but somehow hanged in the finish connection between the client and Appsync server.

When I look into my database while the connection is hanging, the data remains not updated. But when I delete my App process and restart again, the update will be validated. This situation happened both in ios and android, but seems to work fine in web browser.

Which versions and which environment (browser, react-native, nodejs) / OS are affected by this issue? Did this work in previous versions?

"aws-appsync": "^1.7.1",
"aws-appsync-react": "^1.2.6",
"react-native": 0.55,
 "react": "^16.3.1",
"expo": "^30.0.1",
 ios : 12.1.2
 android: 8.1.0
