Color challenge 5 Liliana Vess results in Network Error everytime I try to play. Please HELP

No puedo continuar Jugand9

I cant participate in all color challenges.
When I press the challenge button, it shows a network error on the screen.
Such symptoms have continued for more than half a year.
Fix it quickly!!!!!!!!!

ACTUAL FIX: All you have to do is click the deckbox to open the editor, remove all spells from your deck, and add enough basic lands to make 60 cards, then play (lose) your game. Once you're done, should you ever attempt the same challenge match again, you will find that your deck still contains only basic lands no matter what the editor tells you nor how many times you try to edit it. HOWEVER, YOUR CHALLENGE WILL BE RENDERED COMPLETE, YOU WILL RECEIVE YOUR REWARDS, THE DECK WILL BE UNLOCKED IN THE EDITOR, AND YOUR CRIPPLING O.C.D. WILL AT LONG LAST BE QUELLED. If that's all you need to know, you can stop reading now.

The rest of you nerds out there can keep on reading as I explain, braggadociously, all about how I figured this out in about 30 minutes of tinkering while all the rest of internetdonia has been left scratching their heads for literally months. The first thing I noticed upon receiving the error message and checking my deck editor was that my deck only had 59 cards, and any attempts I made to fix this were met with an error message saying I had illegal cards (which was clearly false, as I had just joined Arena as a new user and had only the cards they gave me). I began removing cards from my deck one by one to see if the error message went away. It turned out that my hunch was correct: despite the glitch, the game still recognized basic lands as being universally acceptable. From a programming standpoint, this is probably a side effect of there being no limits to their play in any format (besides Commander where they are limited only by color identity and deck size requirements). It probably just made sense not to script any error message code for the basic lands to begin with in the off chance of (wait for it) some sort of bug that might make an otherwise acceptable deck fail to load properly.

Please comment below (above) and let me know if this fix worked for you, because it definitely did for me. As simple and effective as it is, I am honestly amazed that no one else seems to have figured it out sooner.

iOS I finished all the color challenges except for the last step of the black challenge due to a network error.

I was able to go to settings -> account and at the top there was a button "unlock all game modes" and that worked. Maybe give that a shot.

I too experience the same error, and it is kinda frustrating. I managed to do the White Deck and Blue Deck PVP Last battle, but then the error kicked in.

The same bug is occurring.
Even if I check it the next day, it has not improved.
