Program an option to turn off images entirely and just use text to search through the library. That would solve the problem for the bad cached images.
My opinion as made in my other post here still stands. Months and months and months of time and no fixes of any sort have ever been attempted. This is what we call an orphaned program.
Fix your products please. I say please because I actually love anime and want to enjoy it. But I'm not blind. I can see how little any of Crunchyroll's staff take time to comment. I can see how long it has been since there was an update to the software. I can see how you throw new versions out there to new devices. But spend no time at all to fix your older software. Which means, I might as well stop complaining here and start complaining to Sony about your product.
