Been a while since my last post as well, but I took My 2020 Titanium Hybrid in about two weeks ago, and they are currently replacing the transmission. It is expected to be ready tomorrow! yay! This is the second time I've had to take it in; last time, they spent a bunch of time doing software updates and replaced the flywheel, which seemed to fix the issue for a few days. The dealer said they had seen quite a few hybrids with this issue (which is probably why they decided to swap out the entire thing instead of doing software updates for days like the last visit. Hopefully, this is the end of this issue; fingers crossed.
