Hi,

I have an issue with installing paid apps from Playmemories. I've bought Bracket Pro. The transaction went through fine—I can see it on my credit card statement, and it appears in the "My Apps" section of the site.

Whenever I try the install though, I get the message below:

Unknown error.
Please disconnect the USB cable, power off the camera, reload this page, and try again.
(# 9900)

If I try to install it directly on the camera I get the following message:

The refund process has not been completed. Please wait for a while. Thank you for your patience.

I'm not aware of having requested a refund, so that one just seems bizarre.

I can still install free apps easily, just not the paid one.

Camera: ILCE-7RM2

Tried install with MacOS/Safari & Windows 10/Chrome.

Any ideas what the problem is or how to fix it?

Thanks,

Nick
