Digits Login and 2fa on Web Client

I see there’s no option to edit the original question / post, so I’m adding a follow-up:

The web client for Digits is effectively useless.  The glitchy, random behavior seems to be getting worse.  Among the issues:

• Repeated auto-logoff at random time intervals.  Could be minutes, could be hours, could be while you're actively using it.
• Full password, 2fa, line registration and preferences setup *every time*.  It doesn't even remember your device for 24 hours for 2fa or remember your registered lines or preferences.
• Message syncing is not consistent or timely.  I'll hear the message notification on my phone but the new message(s) doesn't come up on the screen in the Digits web client.
• Messages don’t go out on the first attempt and you get a “retry” prompt.

It worked reasonably well until a couple of weeks ago.  I was messaging back and forth with a friend this morning and was literally typing into the message window when it logged me out and I had to repeat the whole login and setup process again, and this was shortly after a prior auto-logoff.  At this rate it just doesn't pay to use the web client.  What's weird is that the app on my Android phone seems to work pretty well, but the web client is garbage.

As an aside: I spoke with T-mobile tech support.  Total waste of time.

Does anyone have any experience with any alternatives for use on a Windows PC?  It's so much easier to message on the computer while I'm working instead of picking up the phone every time to read and reply to messages.
