Suppress urldate (apacite)

Question

I'm using apacite package, and I've been trying to suppress the url when the doi is available, following the solution provided by Linebreak in url:

documentclass[11pt,a4paper]{article}

usepackage{hyperref} 
usepackage{apacite}
usepackage{etoolbox}
usepackage{environ}

newtoggle{bibdoi}
newtoggle{biburl}
makeatletter

undef{APACrefURL}
undef{endAPACrefURL}
undef{APACrefDOI}
undef{endAPACrefDOI}

longdefcollect@url#1{globaldefbib@url{#1}}
longdefcollect@doi#1{globaldefbib@doi{#1}}
newenvironment{APACrefURL}{globaltoggletrue{biburl}Collect@Bodycollect@url}{unskipunskip}
newenvironment{APACrefDOI}{globaltoggletrue{bibdoi}Collect@Bodycollect@doi}{}

AtBeginEnvironment{thebibliography}{
 pretocmd{PrintBackRefs}{%
  iftoggle{bibdoi}
    {iftoggle{biburl}{unskipunskip doi:bib@doi}{}}
    {iftoggle{biburl}{Retrieved frombib@url}{}}
  togglefalse{bibdoi}togglefalse{biburl}%
  }{}{}
}

begin{document}

nocite{*}
bibliographystyle{apacite}
bibliography{references}
end{document}

In the references.bib have the following citation:

@misc{american_cancer_society_melanoma_2018,
    title = {Melanoma {skin} {cancer}},
    url = {https://www.cancer.org/cancer/melanoma-skin-cancer},
    urldate = {2018-02-20},
    author = {{American Cancer Society}},
    year = {2018}
}

I'm facing the same problem pointed out at the end of the thread, which was not answered:

The solution does not seem to work well if the entry urldate (or lastchecked) is defined (and the DOI is not). The reference would show up as Retrieved from [2018-12-20]http://www.example.com

So after using the code provided, I would come to this:

Is there a way to suppress or reformat the urldate?

BottleNick · Answer

Yes, @pablos' and @Guido's solutions don't account for the optional urldate. To make it work, insert this (the original definition of the APACrefURL environment in apacite.sty):
newcommand{APAurl}[1][]{%
  ifx@empty#1@empty
    BRetrievedFrom%  Retrieved from
  else
    BRetrieved{#1}%  Retrieved <date>, from
  fi}%

and replace this line:
{iftoggle{biburl}{Retrieved frombib@url}{}}

with this:
{iftoggle{biburl}{expandafterAPAurlbib@url}{}}

I also spotted a bug in the previous solutions, which resulted in not printing the DOI if no URL is available (weird, right?). For this, you simply need to replace this line:
{iftoggle{biburl}{unskipunskip doi:bib@doi}{}}

with this:
{unskipunskip doi:bib@doi}
