@danilo1998271 When using a string uid, there is no issue with web-to-web communication. However, problems may arise when communicating between web and native platforms. It is recommended to use a numerical uid to avoid these issues. Maybe we will fix this issues in the feature.

Is there a work around in our case we need to use string uid in our unity app and in flutter web?

It's so sorry that there's no workaround for this issue at this time.
