[AC Question]

The new build ruined predictive text - it's really bad now. Please roll back or fix ASAP.
1) Dictionary is filled with "junk" words or partial words like "orry", "an d", and "ack5". These may be meaningful to someone somewhere, but probably not the majority of the population.
2) It is impossible to delete 1-letter words, like "e", "t", etc. Long-press does not work. Some of these are ok, but filling up the options with nonsense doesn't help us type faster.
3) Dictionary reset takes me back to point #1 (dictionary full of junk)

HELP! For those who use this feature, this release is a productivity killer.

Hi there,

Which build are you referring to? A new OS for a specific phone? A new keyboard app build?
1) That sounds more like added words from mistypes (learned words added to your personal dictionary). Most keyboards will let you long-press on the suggestion and let you remove it from your dictionary.
2) Is that being suggested or is that the letter you just typed? Single letters cannot be erased because they're not part of the dictionary, they're just typed letters (and suggestions based on historical taps).
3) Are you syncing to other devices? If so, try un-syncing and then doing a dictionary reset.
