The disappointing answer is: it depends. It depends on the reason for discontinuation. Take for example: “International Journal of Pharmaceutical Research” (http://www.ijpronline.com/ ) that used to be indexed in Scopus https://www.scopus.com/sourceid/19700174645
Looking at the Scopus content coverage it is clear that they published (on average) 40 papers each year. In 2018 it was all of sudden 256, in 2019 690 papers and in 2020 a staggering 2577. This disturbing increase in published papers is often a reason for Scopus to discontinue. One of the reasons is (presumably) that they question whether a journal can cope with such an increase in terms of serious and (high) quality peer review.
It is a matter of wait and see whether they will stop coverage in 2021, in 2020 or in 2018 where the sudden increase started. In this particular case my ‘educated guess’ would be: at least coverage till 2019, but the way Scopus operates in these matters remains somewhat unpredictable.
In the case of so-called hijacked journals Scopus is somewhat more predictable. For example in the case of “TEST Engineering & Management” https://www.scopus.com/sourceid/12997(in principal) ALL papers published in the hijacked version are removed and no longer Scopus indexed (though Scopus is still busy to ‘clean’ their database).
