Luckily you can turn off the redesign in preferences with an account. You can use old.reddit but that's pretty annoying imo. The redesign is truly terrible and having 2 UIs, one of which has many strange user engagement oriented features, is very odd. Old users are used to their old ways and stick to them, never really seeing the totally different world new users see.. This causes an odd divide in user behavior. I have heard mods complain about this as their members will be complaining to them about things the mod never sees since they prefer the old design.
Also yeah, the way they intentionally murdered mobile browser access infuriates me to no end. Truly a prime example in "how to get users to migrate platforms by totally degrading the old one and pissing the users off as much as possible'. If you googling something on your phone and open a reddit link, you'll first hit an entirely useless amp link that tries to get you to use the app. Then you subvert that and get another useless page that tries to get you to open the app. Ignore that. Oh, you can only see 3 comments and couple layers deep but want to expand the more replies. Ok, press expand. Oh, I am in the app store now. Truly some cancerous design.
