I guess you encountered this problem when using uniApp. I had the same problem before and created pinia-plugin-persist-uni based on this project to solve the problem.

It seems that your approach is not quite the same as mine, but you can refer to it.

我猜你在使用 uniApp 时遇到了这个问题。我之前也遇到过同样的问题， 基于这个项目创建了pinia-plugin-persist-uni来解决这个问题。

看来你的做法和我的不太一样，不过可以参考一下。
