Topic: Two seperate eshop balances?

Hi all.
I've noticed something odd, I recently linked my Switch to my Nintendo Network account, Facebook etc. all to the same thing. I went to digitally buy a game on my Switch but I had no money ($0.0 funds) on the account but on my Wii U and 3DS I clearly have $30 of funds still left.
It made me think my accounts where not all linked up and I checked but they still are, I couldn't find anyone else having this sort of problem as well. Is this a thing they haven't introduced yet, allowing funds between all three consoles? Or am I missing something here.

Yes, I've experienced that problem once on Switch. Sometimes the balance doesn't show up correctly on either device (Switch/3DS), though I could be mistaken. Restarting the eShop or trying again at another time generally alleviates the issue.

Go to add funds, it should then give you an option to merge funds. I faced this issue when I picked up my Switch

I've experienced this problem after merging my funds though. The balance would simply display as $0.00. It hasn't happened since, but it is a problem that may still affect some users (time to stabilise the Switch?).

Thanks for the replies all, I have tried resetting it a few times and didn't seem to work. I remember seeing it when I first started e-shop when I first loaded it up but I've never used it since till I got a new e-shop card. Might have to give them a call. Thank you all for the help though!
