I would like to report a potential issue I encountered in MTG Arena.
When I selected a Jumpstart packet, the generated deck contained 27 lands and only 13 non-land cards, which appears to be incorrect. Unfortunately, I was unable to save a screenshot, so I do not have visual evidence. I am also not requesting any form of compensation; I simply wanted to report the issue.

Additionally, I noticed that some of the rares I selected from other Jumpstart packets were not registered as acquired in my collection.

Could you please confirm whether this is a known bug or provide any information regarding this behavior?

Thank you for your assistance.

Same bug here. I had picked my two packs but then a 'waiting for server' loading screen which took me back to home page.
Now when i go to play jump in i see as screenshot attached, but note the greyed-out confirm button.
Restarting gives the same result.

same. open ticket was closed after submitting the rrorlog... great
