Multiple Data Layers in ArcGIS map

Hi, xyz9809 
Thanks for reaching out to the Microsoft fabric community forum.

Regarding the issue you raised, my solution is as follows:

1.First, regarding your initial question, you might consider clearing the reference scale. Below is a screenshot from the relevant documentation:

While reference scales are very useful when designing printed maps, you may want to disable this behaviour when using interactive and web maps. Typically, multi-scale web maps adjust symbol and text sizes for each map scale.

For more details, please refer to the documentation:

Symbol units and size—ArcGIS Pro | Documentation

2.Secondly, the time slider requires you to add a time field in the Time field well. Below is a screenshot from the relevant documentation:

I hope this information is helpful to you. If you have any other questions, feel free to let me know!
 

Best Regards,
