People were spreading misinformation about the link. Just to be clear, there is no recall. The test is not defective. The test can be used through the end of the year. The CDC recommends using tests that can detect flu as well as COVID.
The current PCR test from the CDC does not detect flu at all, or other coronaviruses. The test is very specific. See pages 40 on in the Instructions for Use[1] if you are interested. The test sequences were compared (by computer) to hundreds of thousands of genomes of flu, the human genome, and other organisms, as well as tested on physical specimens.

Here is a sample of messages that were shared on Reddit:
> The FDA announced today that the CDC PCR test for COVID-19 has failed its full review. Emergency Use Authorization has been REVOKED. The FRAUDULENT PCR Test has finally been ruled a Class I Recall. This is the most serious type of recall. All measurements based on PCR Testing should come to an end ASAP:
> CDC retracts PCR test as it can't differentiate between COVID and the flu. It was all a Lie.
> CDC pulls PCR tests because they can’t distinguish Covid from the flu. We finally caught the SOBs who have lied to us about the coronavirus numbers the last year.
> The Pandemic narrative is unravelling... The FDA announced today that the CDC PCR test for COVID-19 has failed its full review. Emergency Use Authorization has been REVOKED. It is a Class I recall. The most serious type of recall. Too many false POSITIVES. This is the test that started the pandemic!
> CDC to Withdraw Emergency Use Authorization for PCR Test Because It Cannot Distinguish Between SARS-CoV-2 and the Flu.
> Watch the panicked minority bombard the comments with establishment talking points to try and refute this tweet.. PCR is being rescinded as a test, vaccinated people are filling hospitals, and our government officials are still urging us to get tested using PCR and get jabbed with the Covid vaccines. Alrighty then.
