Secret token in cookies invalid

Does anybody know why whenever I open Manager I get the following message?
Error: Secret token in cookies invalid (5c0171a0-19b1-485e-88e7-4a4336a10cee)

I assume this is desktop edition, right?

@sia - please also mention which version of Manager you are using? Did you just recently download an update, or has this happened suddenly for a version that was previously working?

@sia, try the latest version (17.9.93). The issue should be resolved.
