Update April 29: You have to update Feather wallet, it fixes a previous minor error with sending Monero. This new version is 2.6.7, and I confirmed it works. Your funds are safe. Update right in the wallet. Spread the word.
Original post: I do not speak for the developer, I am just spreading awareness to reduce panic and help.
Feather wallet has an issue. Version 2.6.5 may potentially get a failed transaction on sending funds. Version 2.6.6 has issues with starting up on Linux. Your funds are 100% safe, you can even import the exact file to a different wallet, and not have to resync.
Developer has the fix, it’s being built, he’s getting a couple hours of sleep. No need to panic, it’s a minor issue that will be resolved shortly.
Let’s all thank dsc & tobtoht for their hard work!
Yeah, I hadn't had any issues with 2.6.5 then all of the sudden did. Failure to construct transaction errors. So I'm wondering the same.
There is now some explanation on https://featherwallet.org/changelog/
Looks like it was related to the TX spam.
Thanks. More info to come in the post-mortem too when released it looks like.
