When restarting the new beta version I get the notifaction that some add-ons are outdated and I need to update them. However, when clicking on yes there are no updates available. This happens on every new start of the app, on iPhone and on iPad.
Same here, I think it's also correlated with the "Initializing..." dialog appearing during start-up. The first two or three times I launched 3.99.1.8, it started very quickly and without the "Initializing..." dialog.
If you just click 'no' on that dialog it won't keep reappearing. The problem is due to having outdated graded readers for which we haven't released updates yet. (we'll turn it off in the next beta until we do have updates for all of them)
