Last time I was traveling was in March. After this had same issue but it fixed itself.
Yesterday it randomly showed me the "oops" message on redeem page. I've contacted support and received generic answer that I am either outside the country or using VPN / Proxy.
I don't use proxy or VPN, and I'm not travelling as well.
Today I was able to complete my daily set. After doing so it showed me the same message. However on redeem page everything worked fine. Was able to redeem some points. After 4-5 redeems on this page as well it shows "oops".
This whole points program as well as approach from support is a joke. I've messaged support again, however have no faith that it will be resolved.
For me it looks like support gives you the easiest answer possible without even properly checking what can be causing the issue.
