Worst update process ever. 3 weeks: buggy, annoying, opaque

I really have to express something I'm unhappy to say, because I love the Tandem pump that has been my constant companion for more than a year.

But this update process has been unacceptable. I don't think you have achieved safety by doing forecful, repetitive, redundant training which obfuscates the eight facts you MUST know amongst regulatory garble and repetition of obvious information. It is also a slow and annoying process; I've had no CGM sensor on my pump for more than a month.

Finally, the website is unreliable and the same login information (saved by my browser) will sometimes work to log in and sometimes not. Click four suddenly lets you log in.

Tandem, I love you, but developers, please have a patient run through the entire process with you in front of them. Then, you'll see how users fare and the grief, frustration and dead-end moments they experience. This is just not acceptable.

You also fail to caption your videos - it's also non-inclusive. Anyone who is deaf, uses a screen reader, or has any reasonable human need to have more than audio it interact with is up the creek.

t.Slim Update w/G6

Big Kudos to both T.Slim and Dexcom! From the new innovative technology, the simplicity of the update instructions, and the excellent assistance from the support desk…GREAT JOB! I especially love the new sensor application device. My iPhone’s battery life also wants to thank you…(don’t need to use the app on the phone anymore)

Keep up the great work…and thank you for making Type 1 a better place to live.

Dont update on a weekend

Did every step and when I got to press “Update”, the spinning wheel of no action is present for HOURS, while I sit waiting for customer support to call me back. Frustration both with the update software and slow customer support.
