Glad I'm not the only one suffering, misery loves company after all.
Got the following back from a rep:
'We are having a high volume of tickets.
Sincere apologies for the issues you're seeing, and thanks so much for your patience working on this.
We just finished to fit the video player update with the upcoming AWS Crunchyroll Migration,so we’re now starting the rollout for this HTML5 player sooner than was expected.
Any issue will be fixed very soon.'
I'd unsub in protest, but it seems a little pointless since I still have 7 months left on my yearly sub...
