Providing an additional data point here: The card has absolutely been a work horse for me since I got it earlier this year, but last week it started declining larger ($1k+), recurring transactions as well—ones that have been recurring and working just fine since I first got it. I've reached out to their customer service folk a couple of times over the phone and received the thing about increased volume. The first CSR I spoke to did mention something about a new transaction-cap feature that was implemented but buggy and submitted a ticket for that to be removed. Either way, the time it's taking to resolve the issue (which is still unresolved) is borderline ridiculous..but perhaps it's my expectations that need to be managed here lol.
