I create a website where a user needs to to fill in a form. After that the form starts to call an API with this input.
Unfortunately the API response is very slow and sometimes user has to wait about one minute.
I have read from UX Movement that if the user needs to wait so long it is better to use a progress bar instead of a spinner.
I cannot predict how long the api call will last. Therefore, an accurate display of the progress is difficult.
Do you have any experience or ideas how to handle this?
