I had been using Pleco with no problems for about 3 years on a RealMe brand phone that I purchased in China. I used the Google Play replacement Aurora Store to install the app and regularly update it. When trying to install the most recent update via Aurora Store a message pops up saying that the apk is corrupt and suggesting that I search for a replacement app in the phone's native RealMe app store. I'm able to cancel this message and install Pleco, but when I launch the app it immediately closes. Has anybody else encountered this problem or have a fix to suggest?
