Right now, I have two different rewards-accounts simply because you block new devices. I have four devices of which one recently had win 11 installed (and thus counts as a new device). This meant I came over your four devices limit - although I only have four. Uphold has told me to contact you about this issue as it is your rule.
Other software also have such limits, eg. Microsoft Office, Adobe, Netflix, and Dropbox. But they let you delete old devices - unlike you do. Why is that?
Right now I have an unlinked Rewards-account on one device and the rest linked to an Uphold account. That is not very smart, and it cannot be so hard to add a “delete” function to the registered devices.
