Thank you for tracking these bugs so diligently over the years — this kind of persistent monitoring is genuinely valuable to the community.
It's frustrating when long-standing bugs persist through multiple updates, especially when there's no official acknowledgment. For what it's worth, a few suggestions that may help push Apple to address these:
1. Submit each bug individually to Feedback Assistant
- https://feedbackassistant.apple.com
- Apple's engineering teams are more likely to act on individually documented bugs with clear repro steps than general mentions in community forums
- Include your Numbers version, macOS version, and a minimal spreadsheet that demonstrates the bug
2. Duplicate existing Feedback reports
- If you've already submitted reports in the past, re-open them in Feedback Assistant and add comments noting they persist in 15.3
- Feedback with multiple duplicates gets higher priority
3. Consider posting specific bugs as individual threads
- Breaking down specific bugs into separate discussion threads may attract more community attention and "Me Too" votes, which can also signal to Apple the scale of impact
And for the WEEKDAY function fix — good to hear that one finally landed, even if it took a while. Hopefully the remaining items on your list get addressed in the next release.
