It only occurs in flickr and only when selecting "my groups".
I'm dubious of remove & reinstalling, because I can't see it on the list of available channels. I only just linked it to a flickr account a few minutes before these crashes started. So 1, the linking worked flawlessly and 2. before this there were no groups (so the icon was "decorative only")
Thanks for the reply.
The channel developer themselves maintains channels on Roku. We suggest reaching out to the channel provider's customer support team to report the issue and get help. There might be an issue on that 'My Groups' icon within the channel that needs to be addressed with an update from them.
We appreciate your understanding.
All the best,
Kariza

I am sorry for the trouble here. Roku made the Flickr app that was available to their customers, we do not support Roku.

So the app is Roku developed and has a simple (Roku) bug . The complicated stuff, like syncing accounts is working.
Thanks for the reply.
It looks like the channel is no longer available on the Roku Channel store and cannot be located in the channel search. If you want more information about a removed channel, please see our support page here: Why is a channel no longer available on my Roku® streaming device?
