Indeed. I installed K-9 mail as soon as I discovered it would become Thunderbird for Android.
Did the same, but I’m not using it until the rebranding occurs.
I’ve gotten used to it, but I’m not a massive email user on my phone, mainly use it for alerts so I know to go chek the PC when I get home from work etc.
Technically, I’m already using it as my daily driver (as K-9 Mail) and so have I been for several years already. What I’m looking forward to, is to get parity with desktop Thunderbird.
Very much so, I’ve been eyeing a new email service and said I would finally subscribe once K-9 becomes Thunderbird.
I thought it was just K9 Mail, is there something else coming up?
So, according to Jason Evangelho (Thunderbird team), when I asked for an ETA:
Currently, we’re shooting for after Thunderbird 115 releases. It could either be late Summer or very early fall. Once we get the Account Autodiscovery module from Thunderbird desktop integrated, we’ll be pretty close to flipping the switch. And we’ll be sure to keep everyone posted on our blog at https://blog.thunderbird.net
