I've already read through the various font licensing documentation. Can you please advise on my specific question?
I doubt the people here would know what a React-based web app is, but also ADOBE STAFF WILL NOT GIVE UNDERTAKINGS THAT SOMETHING IS OR IS NOT COVERED BY THE LICENSE. (I don't work for Adobe).
This is because, if something comes to a law suit, ONLY the terms of the license are considered: not any promises or clarifications. If you need legal advice contact a lawyer.
Or, I suggest, look for a perpetual license. Do you really want your web app to collapse if, for example, you have an Adobe billing problem?
