Update: As Gary Leff from View From The Wing pointed out via e-mail, it’s still available via affiliate channels. Who knows what Barclaycard is up to.
Barclaycard isn’t currently accepting applications on their Arrival+, Arrival or Ring products. Instead it says to check back later to apply (see below).

The last time this happened, Barclaycard made some negative changes to these cards. I suspect more changes are in store, if they were positive changes I don’t see why they would have put a halt to applications. Although it’s entirely possible that no changes are in store and they have stopped applications for other reasons.
Feel free to post your conspiracy theories in the comments below.
