About graduated color settings

[-_-]

Regarding editing break values ​​for quantity-driven symbols such as graduated colors or graduated circles.
Has this ever happened to you?

1. The upper bounds were automatically set to "<=2.2,<=12.8,<=17.9,<=25.3,<=39," but I want to set them to "<=10,<=20,<=30,<=40,<=50," so I manually change them from top to bottom.

2. As soon as I change "2.2" to "10" and "12.8" to "20," the symbol is automatically loaded and the order changes to "<=10,<=17.9,<=20..."

3. If I then accidentally change the second-placed "17.9" ​​to "20," one class will be lost. I'll have to change the spacing back to "Manual" and start over.

4. I need to make sure I don't accidentally overwrite "20," but since the color order has also changed, it's hard to intuitively know which upper limit to rewrite.

I need to change the upper limit value many times, and every time I do, I'm plagued by this "automatic order change function."

I've been putting up with this hassle for years, what do you all do?

Is there an easier way? I'd appreciate it if I've overlooked something.

I wish it were like ArcMap, where you click "Apply" after setting everything up and the symbols are updated.

I don't have Pro to test but from

Graduated colors—ArcGIS Pro | Documentation

way down under...

Modify graduated colors symbology

    From the More drop-down menu, you can perform the following tasks:

Turn on or off automatic class label updates

Click the More menu and check or uncheck Always update class labels to control whether the labels of each symbol class are updated automatically or manually. Unchecking this option can be useful if your class labels are descriptive in context or do not frequently change.

Does that apply?

That feature was requested, got a lot of support, and was resolved a few years later.

However, my issue was with editing the upper limit of symbols, not labels, so I don't think what you've suggested applies.
Unless I've missed something.

I have encountered this issue as well, where ArcGIS pro automatically reorders my graduated colours list. My suggestion is go slowly. Use the Method drop down to get a distribution close to the one you want (e.g. defined interval in your case). Then go back to Method and choose manual interval for fine tuning. Fewer things to change.
