Hm I wonder then if it's the update itself on your device that is failing. You might try to clean the table without going through the balance recovery as follows: 1. Backup seed and send your balance to another ecash wallet (like web based cashu.me) 2. Uninstall then install from direct link (github or zapstore cdn, I've tested both) 3. Start the wallet, move balance back 4. Go to Settings > Recovery > Seed recovery > Wallet address and use your seed phrase to get your former wallet address back.
