@danielletully I have the same issue. Are you running a custom data hook?

I noticed that the loading indicator of the "next" button wasn't triggered when the function wasn't called asynchronously.

Here's how I managed to resolve it:

selectHeaderStepHook={async (
    headerValues: RawData,
    Data: RawData[],
  ) => {
    const d = await new Promise<{
      headerValues: RawData;
      Data: RawData[];
    }>((resolve) => {
      setTimeout(() => {
        const result = doCustomDataMapping(
          headerValues,
          data,
          params,
          fields,
        );
        resolve(result);
      }, 0);
    });
    return d;
  }}

By making the selectHeaderStepHook function asynchronous (async), and awaiting the promise creation using await, it ensures that the loading indicator functions as expected even with the slight delay introduced by setTimeout.

@benzler Thank you so much!!! This worked for me!
