I'm bumping this for a question: 2 days ago, Google Play informed me about an update.
Since then, Bluewallet doesn't work anymore. I see the logo, followed by a white screen. I have my backup seed, but that's for the Bitcoin addresses. I have only a smalla mount of Bitcoin Lightning in the (custodial) wallet, but I can't find if that's somehow linked to my wallet seed.
Have you tried clearing the app cache? It sounds like the usual play update that somehow messed up the app data. You might want to back-up the app data with Swift Backup or something similar, uninstall it and then reinstall an older version that works fine for your device if you still want to use it. But well, I can't guarantee anything.
What Android version btw?
