I find the new Custom Field layout on Mobile 3.0 Task View to be far less productive and easy to use than the 2.0 version.
Having to scroll right, whilst also checking multiple rows of custom fields, which are also truncated, is a really slow process.
Further, it's completely different to the desktop version, which is vertical.
I don't really see a problem with the 2.0 version, which was vertical like the desktop version, respected the order set on desktop (which mobile 3.0 does not, especially with there being 2 or 3 rows), did not truncate anything, was quick to use, made it visually very clear and easy to see which custom fields were set and with what values, and was overall a far faster, more productive, and information-rich way of entering and viewing custom field entries.
It feels a lot like change for change's sake, rather than being a productivity-boosting decision.
I would really like for it to just mimic the desktop set up - i.e., show pinned items, regardless of if they have entries, show non-pinned items that do have entries, then click "see more" to see custom fields that aren't pinned and have no entries. So basically how it was in Mobile 2.0 Task View.
It's fast and it works.
