Why is "Afterwards I am tidying" marked wrong here? Surely the preposition isn't necessary for the sentence to make sense?

Could you also say "Later I am tidying" ? It gives later as one of the options for wedyn, but did not allow that for the full sentence.

Hi - could you please add 'afterward'? We use afterward/afterwards pretty interchangeably here, and I forget it only accepts 'afterwards' and get it wrong every.time. :) Thanks.

yeah i think the reason this sounds so weird is in english if you speak about the future (later, then, afterwards) you will invariably use the future tense, but in this case that's incorrect

I said Tidied up ?

I have put i am tidying and got it wrong.

That sounds really awkward, what about " I will tidy up later"?
