In Star Trek Discovery S1:E3 Context is for Kings we see the USS Glenn, which contains the mycelial plane experiments and dead crew.
We learn (from Saru) that it is not possible to transport the experiments to the discovery due to lab shielding, so the crew will have to go across to the USS Glenn.
At the end of the episode, the tardigrade has been transported to the USS Discovery.
Indeed, the following commentator writes:
In this ep, Saru says the shielding of the test lab on the Glenn prohibits using the transporter to retrieve the project materials. yet we see the guest on board at the end
My question is: Why can Discovery transport the tardigrade at the end of the show when at the start the shielding prevented them?
