Link to OMNR?? Dunno why I failed to find anything related to it!
I saw you were asking about getspendl in the past but it doesn't seem to be fully working? There isn't any update from them in Bitcointalk from a year now...
For Advcash, it doesn't seem their card will be available before Q3? 2021 imo..
My bad, as stated above, it's OWNR:
https://card.ownrwallet.com/You'll have to create an account before being able to access most of the details related to the card.
As for GetSpendl, have you tried contacting the support? IIRC, they were very responsive whenever I reached out to them asking for details.
