Be careful with updates. I had some sats in there and the app updated and then the sats were gone. Thankfully it wasn't much

Is there a way to backup?

I had my seed phrase backed up but restoring it didn't solve it. As it's custodial and I didn't have a large amount in the wallet i didn't pursue it further. so idk

I must've skipped all of that in the onboarding and now I can't find it any more. @Minibits heeelp

You'll find the seed phrase in settings. Keep it somewhere outside the device. Recovery from seed is last resort, mostly in case you lose the device. For other wallet hiccups that might come due to heavy both protocol and wallet development, there is still local backup of ecash in separate database that can quickly help in some cases. Enjoy and keep only small amounts in ecash and in r&d focused wallets.
