Thanks for your report!
There is indeed a known issue where this button has a very small tap area. (technically it is possible to see more but yeah it is really hard)
While we will try to fix it, we are also testing a new events UI that does not have this button anymore, as part of our updates to event discoverability.
Here’s a couple of screenshots of what this experience will look like with the new UI:
Unfortunately at this time we’re not able to say definitively whether the “See More” button will be fixed before the new UI is rolled out to all users, but rest assured that users will easily be able to see all events soon!
