I'm on Lifetime account as well since early this year, and I do not prefer the auto-track. I've tried Aftership and sometimes the can mix it up as local and international delivery may have the same tracking format. Especially those with numbers and same number length.
I guess it's more on one's preference? This has hiccups as many tracking apps out there, but it works the best for me so far.
What you can do is, you can actually type part of the courier's name and it will list down the list related.
Attached is the screenshot from my phone when I tried to type DHL into the search bar.
