Time Slider showing No Time Extent Warning

[Ed_]

So I have created a time slider Instant app from a time enabled web map. Now the thing is as you can see there's this `No Time Extent` warning on the slider. This warning goes away when I drag the slider to start. 

Three questions:

1. How can I make this warning go way?

2. What's causing this warning?

3. How can I make the slider default to the start?

Warning goes away when I drag the slider to the start:

Does the warning still show up outside of the configuration experience when you publish and launch the app?

I am experiencing the same issue. The "no time extent" error is appearing on my time slider whether it's launched directly or opened as embedded content in an Experience Builder. The play button is also grayed out. The error disappears and play button activates when you drag the slider forward and back to the beginning. My app was working fine early last week and no changes were made. Hoping this issue will be resolved soon or there is a fix we can implement on our side! Thanks.

Hi @MilanLiu or @Ed_ , did you ever find a fix for this? I am experiencing this issue even though Esri reported it as a fixed bug: BUG-000163480 for ArcGIS Instant Apps
