I can’t download cashapp and other apps on my iPhone
How can I get cashapp on my iPhone 6
What happens whan you try? is your iPhone storage okay in Settings>General>iPhone Storage?
If your iphone is updated to the latest compatible iOS version (now 12.5.2), since that app is exceeding 200MB size, is your iPhone connected to a reliable and fast wifi network with Internet access?
