I have blockfolio on my iphone. I have it for years and i notice for a long time., when you click on home, it shows all the coins you are tracking... but they are not up to date. Example you need to click on btc, and then it will immediately show you the current price. But whne you look down on your coins like bch and other coins, none are updated. You need to manually click on each coin in order to get the current price. Is that how its been for a while? I notice this issue for almost a year i believe. I do update it when it needs an update.
Any other apps like blockfolio that isn't lagging? I like it but i find it annoying i need to click on every coin to find the current price. I mean back then i recall you click home, it updates all the coins in your portfolio.
Blockfolio takes a really long time to refresh data (I am used to it) and by the time it had finally refreshed the data the price changes already. For real-time quick updates try using different portfolio management apps. As soon as you open you need to refresh the app by sliding finger down (iOS)
