UPDATE 25/09/2020 : 'An asset error occured during your last play session. Validating asset files to ensure stability, this may take a while.' Followed by a very long verification of assets.

Issue still happening every day when I first launch the game, even after updating video card drivers, I still have the same problem.
Started happening 2 updates ago, I thought your last update would fix it but no. I took my first screenshot of the error September 19 2020.
I managed to reproduce the error.
Please note, if I launch the game, wait for the assets to verify then close and reopen the game I do not have an assset error, I tested this several times.

If I play 'play standard' game then exit and reload MTGA, I do not have the asset error.
If I play 'Standard Ranked' then exit and reload MTGA, I do not have the asset error.
If I play 'Quick draft Ikoria' then exit and reload MTGA, I do not have the asset error.
I played till I won an Ikoria card reward, then exit and reload MTGA, I do not have the asset error.
I played till I won a zendikar card reward, then exit and reload MTGA, I do not have the asset error.
When I completed an Ikoria quick draft and opened my Ikoria pack reward, then exit and reload MTGA, ERROR ERROR ERROR....

Now I get the error screen again ' An asset error occured during your last play session. Validating asset files to ensure stability, this may take a while.'

To be clear, I was not using any addon's or trackers or any other application, the only thing open on my computer since I rebooted was MTG arena.

Presently using Magic the gathering Arena Version 1.1200.4.3152(3152.817437)
On windows 7 Home and windows 10 Pro. Same issue on both machines.

If you need more information please contact me.

Other errors I noticed in the game... the display of Ranked info after a non-ranked game appears to be resolved and not happening anymore.

There are still issues with the emotes in game, if an opponent selects nice, my side has a thanks response, when clicked thanks it says nice on my screen instead. So that still needs some work.

I have the unsanctioned land art. It no longer shows up in my collection or deck building. In decks that I already had them in, it shows the sleeve art for basic lands and won't let the land be played during a game. All you have to do is play the unsanctioned lands in a deck, if you can even do that because they can't be found in ones collection. The game just has the sleeve art hover over the field and acts like you played a land but you can't do anything with it. I would like to be able to play with the cards I purchased.

Bug: MTG Arena on Mobile (Android) - Cannot move equipment from equiped creature to another creature

Steps to reproduce the bug:
1. Have equipment and creature on the battlefield
2. Attach equipment to creature
3. Have second creature on the battlefield
4. Clicking on equiped creature "splits" the card and equipment, but when trying to activate the equipment, it'll "merge" the cards instead

Potential complexity: My equipment (Elven Bow) had a Rune of Flight attached to it

Unfortunately, this lost me the game, because my (summoning sick) non-flying creature would have been able to block his (lethal on board) flyer if I had been able to re-equip.

Platform you’re using: Android (Google Pixel 5, Android OS version 11)

Cheers,
Peter

After the Ikoria update, MTGA is really really unstable.
MTGA always crashes whenever I try to visit the store or mastery, open packs or edit decks.
(Actually, it already happened before the update, but now, it happens in 100%. Cannot edit new decks at all.)

I always need restart MTGA when starting a new match.
Sometimes it gets frozen in black screen with no response and does not recover even when I restart it.

I have already tried restart PC and router.
There are no problem in the network speed.
All the other programs are shut down while playing MTGA.
Graphics screen Quality in MTGA is the lowest and the resolution is also the lowest = 768x432. The emote and audio are turned off.
I have already checked the task manager, however, nothing else was running.
Graphics card is set to default.
