Additional Information

I faced this issue as well at other situation such that several actions run at the same timing. For example, when one signal triggers several useTask$ at once and each of them runs different actions.

[genki]

Here's workaround I found for this issue:

Define the function that serializes execution of actions.

let prevAction = Promise.resolve();                             
export const enqueueAction = async (action, ...args) => {       
  await prevAction;                                  
  return prevAction = action.run(...args);        
};

Then call it instead of run(...) like this:

  // foo.run(args)
  // bar.run(args)
  enqueuAction(foo, args)
  enqueuAction(bar, args)

man, I was going nuts with this issue

anyway, this solution seemed to work for me

useVisibleTask$(async () => {
    await firstAction.submit({ data });
    await secondAction.submit({ data });
  });

which is kinda simpler

I think this is a simple and elegant solution. Thanks @AleksKislov for sharing.

But this is not "simultaneously", they are sequential.

I have no context about this discussion, tho.

well, yes, but at least it works for some cases.

But the thing that an action can interrupt other actions is a bummer
