You're not missing anything - that is what happens near the ground. And your suggestions are right. Good technique and good equipment helps but it still happens.
Or if you need to have two hand ascenders try tying something to the bottom of the rope?
Yes, the thumb trick is the key. Also, Andy is right in saying that it's more difficult at the bottom of the rope with no weight on it. However, a lot also depends on the rope you're using - a newish static is much easier than a dynamic rope.
something that can work is to clip a krab thru the safety hole at the top of the ascender and add a sling, then yank from that rather than the handle.
means the device is ideally aligned on the rope (make sure you clip across the rope into the ascender) and its pulled from above rather than pushed from below.
sometimes the lower ascender sticks because youre bending down a bit to pull it upwards and pulling a bit to the side too, putting a bit of slack in the rope.
It'll self feed quite easily once there's a few meters of rope below you. If you're training near the floor you can leave a coil of ~10m hanging at the bottom to help tension the rope a little.
