The phone installed a system update overnight. The next evening I opened the app for the first time since the update. The screen stayed white for almost twenty seconds. Then the login fields appeared normally. No error message was shown and no reinstall was requested.
I entered the credentials and the dashboard loaded at ordinary speed. The balance was correct and the markets updated without delay. The long white screen on the first launch was the only unusual event. Subsequent openings the same evening returned to normal speed.
What the white screen did not affect
No data was lost and no new permissions were demanded. The app retained its previous settings. I used matchexch apk for the rest of the evening and found no further delays. The single slow launch appeared to be a one time adjustment after the system change.
A second check the following morning
I opened the app again the next day. The white screen did not return. The login fields appeared at once. The recovery to normal speed confirmed that the delay had been limited to the first launch after the update.
Short replies when I described the post update delay
I mentioned the twenty second white screen after the system update. Two people answered that they had seen similar first launch delays. One said the pause is longer after major system versions. Another noted that the app returns to normal speed on the second opening. The comments stayed practical.
One precaution that remained in place
I now open the app once after any system update and then close it again before a match begins. The early launch absorbs the possible delay and leaves the app ready for later use. The step takes only a moment and removes the risk of waiting when a game is about to start.
The APK produced a single slow launch immediately after the system update and then returned to ordinary speed. No reinstall or extra permissions were required. Once the first opening was complete the app behaved as it had before the update. The match schedule continued to decide when the icon needed to be tapped again.
