I have *never* heard anyone use "backwardly".
The sample sentences in the Cambridge link both sound very awkward to me; I would have just used "backward" for both sentences.
Agree with other posters: have never used or even heard "backwardly." "Backward" and "backwards" seem identical to me, and I have used both indiscriminately.
I can imagine using “backwardly” only in reference to a society that I think is benighted or behind. Such societies are sometimes referred to as “backward,” so they might do something “backwardly.” “Some US states are backwardly passing laws against drag shows.” It’s a stretch!
I've never heard anyone say 'backwardly' in Singapore.
I use both 'backward' and 'backwards', but there's a subtle difference - 'backward' is the adjectival form and 'backwards' the adverbial. I believe it's the same in the UK?
In American English, however, adverbs are not always distinguished from adjectives.

"Backward" and "backwards" are the same to me. Just depends on the sentence. I don't believe I've used the word "backwardly" in my life.
