Pretty self explanatory but if you are going to continue to use reddit on mobile, switch to one of these options. You will need to have to create your own api key but that is easy to do.

As pirates we are known to adapt to rough seas. There are always methods for us to keep accessing content and reddit isn’t going to be able to stop us.

I recommend creating a throwaway account for this. Sign up as a developer at the above link and then use the key you get from it.
You can also use Redreader. It’s been my main way of accessing reddit for years and it’s actually the only app (that I know of) with the API exception for being accessibility focused and non-monetized. It’s FOSS and has been ad free forever, although I fear reddit will make them start serving reddit’s ads on the first.
