The latest app update should have resolved the issue with the iOS app. If it hasn’t please let us know here Freetrade iOS app update v 2.4.3.
If you experience lagging / crashes in the app then please contact us via the in-app live chat or by emailing hello@freetrade.io. Although that wasn’t the case here, that can be caused by a slow internet connection so we’ll want to check on this for you & see whether it’s that or something else that’s causing the issue
