Couldn't find maps

I just noticed that it’s not possible to search maps. Eventhough I created a new map and then ‘load’ it, no map can be found… Is there any problem in the server side? Or is that because I reached the 50 maps monthly limit?? And for the free account limit, do I get it right that ‘50’ means 50 maps storage, not 50 times creation? which means I can create more than 50 maps if I delete old ones?

It should be a problem in placenote cloud. It’s recovered already.
