Hi @mengshuaishuai 👋🏼 I'm having problems inferring your question here, could you be more specific about "multiple Amplify" ? Are you looking answers for multiple backends for your single Amplify project ? If yes, please refer to this comment here: https://github.com/aws-amplify/learn/issues/293#issuecomment-904766037 Thank you!

Hi I am also interested in this issue.

When building a fairly large amplify project, you may want to manage separate backends for each feature.

One problem is that cloudformation template size is limited to 1MB.

Therefore, I would like to seamlessly access another backend from a frontend app that cooperates with each backend.

Since the application is developed in monorepo, it is an image that each workspace has an amplify backend directory.

I would like to know how to achieve this.

Hello @rnrnstar2 -- we do not currently support this feature. It may be possible to use the workaround linked above https://github.com/aws-amplify/learn/issues/293#issuecomment-904766037, as the limitation against using cookies seems to be applicable to JS-based solutions such as React Native. On Android applications of course you can use something like SharedPreferences to communicate between the various backends. However, you may run into other issues when attempting to do so.

We can take a feature request to provide a more comprehensive approach to this multiple-backend use case, but unfortunately cannot share any timeline details.
