I think the way dropping a trackable in a cache I just logged as found is really counter intuitive.
First select trackable then select the cache I just logged again from the map and then log the drop.
And If you drop more than one in the same cache the whole process again.
I suppose the person who designed this has never dropped a trackable in a cache.
In the real world you don't hide the cache after the find and find it again to drop a trackable.
The old app used the easy and logical way. First you find the cache, then immediately add your drops.
Just like it happens in the real world.
Please think as a cacher when designing your app.
