Ridiculously small text in Revolut app

I didn’t do anything on my phone (nor changed the text size under Settings > Display & Brightness > Text Size) but suddenly, the text size in the Revolut app turned ridiculously small on my iPhone 13 Pro Max. I then rebooted my phone, logged out of the app, deleted and reinstalled it but no success. Seems like the Dynamic Type support is broken. Has anyone had the same experience?
Support agent didn’t have a clue what was going on. I’m running iOS 15.1 with Revolut 8.28.
