I found myself frustrated by a bug that caused the app to freeze during a match, resulting in a loss of progress. The data usage can spike unexpectedly, which limits my ability to play on the go. I like the variety of card games available, but some of the rules are not clearly explained, leading to confusion. Sometimes, the reconnect feature can be a bit slow, especially when I'm in the middle of an exciting round. Overall, it's an enjoyable app that keeps me entertained, but it could benefit from some optimization.
