Mondly Account Progress Disappeared Despite Lifetime Subscription

I have a lifetime subscription to the Mondly mobile app, but I have been experiencing a serious problem with my account for approximately three weeks. I can log into the app and continue with my daily lessons, and it even recognizes me by the letter “A.” However, none of my other account information is visible. My profile and leaderboard sections appear completely empty. I also have a long-running daily streak, which had reached approximately 680 days, but the app no longer displays it.

I continuously receive a message saying, “Something went wrong. Please try closing and reopening the app or try again later.” I tried uninstalling and reinstalling the app. After the first login following the reinstallation, everything returned to normal and all of my information was displayed. However, when I logged in a second time, the same error appeared again, and my profile information and learning progress became unavailable once more.

I am registered on the Mondly mobile app with the email address a******@outlook.com and the username “Ahmet.” Despite having a lifetime subscription and never experiencing any problems before, this recent issue prevents me from tracking my progress, and my profile appears completely empty.

I expect Mondly to permanently resolve this technical issue with my account and restore full access to all of my learning history, including my profile, leaderboard information, and daily streak. I am also attaching a screenshot of the issue to my complaint.
