Yes, I've reported a bunch of these as well. Basically any sort of corporate action (split, reverse split, merger, etc) seems to completely screw up their "gain" calculations, which are prominently displayed throughout their app. This basically makes it impossible to determine your returns, unless you have a paper record somewhere. Many of the cases I've run into here also completely lose the record of what you paid and how many shares it was for. I'm hoping their new home-grown clearinghouse generates my tax info properly...Still looking for a better option.

>And yesterday it was showing results out to Q2-2020 (?).

This could be due to an individual company's financial calendar. For example, Proctor & Gamble (PG) released their 2020Q1 results 2 weeks ago.

Aren't they supposed to only hire these Ivy League super geniuses and ex-FAANG HackerRank masters (I am not in the US so I genuinely don't know)?

It is kind of funny to see these tech geniuses fuck stuff up that non college educated degen brokers understood decades ago.

HackerRank measures your adeptness at answering contrived programming questions.

Not domain knowledge application to keep yourself from unknowingly creating a system that automates Federal Reserve margin trading regulation violations.

Also, given FAANG's current position, (of all being in one way or another under Congressional/regulatory scrutiny) I'd say that HackerRank fixation isn't turning out so hot.
