I’m playing on a 2017 iPad Pro 2nd Generation with 4 GB RAM. (My previous iPad had 1 GB RAM, so when it fell out of iOS support I replaced it with the iPad with the most memory I could get, 4 GB, since I’ve historically kept Apple hardware until it falls out of iOS support.)
I did not try deleting and reinstalling, especially since I saw @SleepingGiant and @KYakerDude were encountering the same issues, but I don’t know what hardware they are running.
