I encountered an issue when trying to open booster packs in the MTG Arena mobile app.

When I tapped a booster pack to open it, the message “Waiting for Server” remained on the screen for an unusually long time. After that, the normal pack-opening animation did not appear. Instead, a popup appeared with only an “OK” button and no meaningful error message.

Tapping “OK” did not appear to do anything. I tried opening the pack again several times, but the same issue kept occurring.

I then restarted the app. After restarting, the booster pack was no longer shown on the Packs screen.

Because the pack-opening animation and card results were never displayed, I cannot tell whether the booster pack was successfully opened and whether the cards from the pack were actually added to my account.

Steps to reproduce:

Open the MTG Arena mobile app.
Go to the Packs screen.
Tap a booster pack to open it.
“Waiting for Server” remains on the screen for an unusually long time.
No pack-opening animation appears.
A popup containing only an “OK” button appears.
Tapping “OK” does not resolve the issue.
After restarting the app, the booster pack is gone.

Expected result:
The booster pack should open normally, the opening animation should play, and the cards received should be displayed and added to my collection.

Actual result:
The opening animation does not play, a blank popup with only an “OK” button appears, and after restarting the app the booster pack disappears. It is unclear whether the cards were actually granted.

Could you please check the server-side transaction or account history and confirm whether the cards from the affected booster pack(s) were successfully added to my account?

This happens around 0800 to 0900 a.m. Japan time.

Thank you.
