Installed Costco's app (yeah - shouldn't :( ) But it is very handy if I forget my Costco card...
Many of the menu options failed to work.
Turns out my NextDNS was shutting it down... looking at those logs there were at LEAST 5 services I was going to have to 'allow' for the costco app to work. Geez....
Since the only time I'd use it is IN a Costco store I didn't allow those services and will use a web ui if needed - other than accessing my card in the store (probably easier just to bring my card).
... one more 'nail' against apps...
