Training platform recommendations- Getting fed up with Fulgaz

[Robbos]

First part of this is more of a bitching/diagnostics rant, advice sought further down.
I've been on Fulgaz for two years, and while there have been glitches, it suddenly seems to have gone downhill since the last upgrade. on my Macbook Pro running Catalina, I spent an hour two days ago mucking around to get the bluetooth to sync, with weird randomness- sometimes it sees the trainer but not the heart rate monitor, sometimes vice versa, never the two. I've rebooted the computer countless times, reinstalled the app, upgraded the firmware on my Elite Suuito, but still it keeps bugging. Today: the horizontal scroll bars don't work (just the lower ones) so I cannot access the different training programs. This already was the case for accessing saved rides, and I had a lovely back and forth with a smug tech 'explaining' how to scroll with a mac (I've been using mac's since 87...).

So why have I stuck with Fulgaz? I love riding to real videos, it's inspiring and motivating. I have zero interest in riding in a virtual mega blocks style platform. I'm competitive enough that I push myself, but don't feel the need to compete against others. Any recommendations for a platform other than Fulgaz? It has to work with osx 10.15. Yup, that old operating system from 2018(!) that pairs well with my non-electric, non-hydraulic bikes
Thanks in advance for the feedback!

EDIT: I should probably mention that what I appreciate besides the real videos are the training programs on Fulgaz, so, I'd want something similar-training programs adapted to my fitness.
