Ewok Cacher

I have noticed lately that caches are missing on the website map. When I use my computer to view caches there are some missing, I know this because when I view the map on my phone with the Cgeo app they are showing. An example of this is in the subdivision of Tuscany in NW Calgary, Alberta, Canada. There is a cache called Lights out (GC8DMBX). I have done some trouble shooting, like checked that the filters are all off, it's not a private cache,it is a traditional cache, it was placed Sept 2019 and has been found lately, tried both MS edge and chrome both but it still will not show that cache. This is not the only an example I have noticed others as well. Not sure why this is happening.

Thank you for voucher. I have tried to enter it but it says the code is invalid.

I've been a member for a few years now and love geocaching. As I'm a student I don't have a lot of excess cash but have always wondered if I should consider getting a premium membership. Does anyone know if there are a lot of premium caches in the Calgary area and if it is worth getting a Premium Member if you live in Calgary? I've heard there is a 30 day trial but it seems you need a code. Do you know where you can get codes?
