Because there is currently a small delay between when a user modifies a card and when that modification is "done", there is a risk of concurrent modifications (a second card is modified before the first is done), which currently leads to an error message.

### **Note**

This feature is separate from <mention class="mention" data-id="41199" data-type="work_package" data-text="#41199">#41199</mention>, which is about adding a loading indicator on the calendar when _loading_ cards.

### Acceptance criteria

* When a user makes a modification (eg. moves, stretches or shortens a card), show a load/activity indicator before the &quot;success&quot; toast can be seen. Begin of the insertionThis toast:
End of the insertion Begin of the deletion

### Open question

I believe there are three ways we currently show something is happening/loading. 

End of the deletion * Begin of the insertionIs blue (Toast/Information)
* Icon: the basic CSS loading indicator (animated, reducedEnd of the insertion Begin of the deletion The skeleton view (that we&#39;re usingEnd of the deletion in Begin of the insertionsize) replacingEnd of the insertion the Begin of the insertionicon onEnd of the insertion Begin of the deletion Add existing panel,End of the deletion the Begin of the insertionleft
End of the insertion Begin of the deletion notification center, and soon in <mention class="mention" data-id="41199" data-type="work_package" data-text="#41199">#41199</mention>)
End of the deletion * Begin of the insertionText: &quot;Updating...&quot;End of the insertion Begin of the deletion The &quot;uploading&quot; snackbar used when uploading files to WPs or comments.End of the deletion
* Begin of the insertionOnceEnd of the insertion Begin of the deletion The basic loading indicator animation (see below).

The most appropriate one in this case is surelyEnd of the deletion the Begin of the insertionoperation is completeEnd of the insertion Begin of the deletion basic one that we show when loading a work package table list.

**Open Question:** Can we make this workEnd of the deletion in the Begin of the insertionbackground,End of the insertion Begin of the deletion team planner? (Considering especiallyEnd of the deletion the Begin of the insertionblue information toast is replaced by the usual green success toast (&quot;Successful update.&quot;)End of the insertion Begin of the deletion limitations of fullcalendar).End of the deletion
