When I open my wallet it displays the balance I deposited 2 days ago.
When I copied my "receive" address from the wallet and searched using that it showed 0.
Hmmm.
Once deposit address is used, ledger app will provide you with brand new deposit address (this is usual approach to help you keep some level of privacy).
So i think you are actually copying this new (not yet used) address.
Try this:
In ledger app click on that incoming transaction (to see more details) and there is button with magnifying glass icon. Clicking on it should open your browser (by default it opens blockchain.info i think) showing you the transaction details.
Check if the receiving address is the same one you are copying.

I connected with an Evercoin rep and shared with them my "receive" address for my DCR wallet and they confirmed no transactions connected to that address. But my DCR wallet shows 0 balance.
...
Just to clarify: by "my receive address for my DCR" you mean their address where you should sent those DCR?
...
I'm wondering if it is some sort of glitch on my DCR wallet. However, I found this DCR blockchain search (
https://explorer.dcrdata.org) and searched using my "receive" address from my DCR wallet...of course it shows a 0 balance, but also showed no transactions. Yet, when inside my DCR wallet the ONLY activity it shows is me receiving the original DCR balance I deposited in it. No transaction out.
This starts to be quite confusing (maybe the same issue as in first point ... address was already used so you are actually copying new, not yet used address).
Could be some glitch indeed. I'm not decred user so can't tell but all wallets should have option to rescan database or something similar.
Try to find that and use it.
EDIT: it really looks like you have never sent them those DCRs (for reasons unknown) thus they didn't sent BTC to you.
