Think of it this way - if it's stated in your contract that you shouldn't and you do it, there may be companies that are more lax, but will use it as ammunition if they need to get rid of you for whatever reason. If there are specific things that limit your typical workflow, maybe worth taking it up with the relevant department first.
I think a lot of group courses/recorded courses don't work/lead people to give up because the context provided is not intuitive to everyone's mind and requires significant googling (or ChatGPT chats) for a concept to click before moving on.
Having that ability to pause and clarify with for as long as needed (and have it dumbed down as much as needed) seems like a step in the right direction.
Question to those who post about work they've done while employed at a large company - how much do you take into account employer confidentiality clauses? Is there a good 'rule of thumb' checklist of rules to tick away ahead of posting?
Some 'neobanks' like Revolut help deal with this type of thing - you can create a temporary card to sign up and scramble it whenever you please. Great for trials or indeed annoying subscriptions.
