newly downloaded app but cannot login. it kept on providing the error below. please note that I am able to login in the web portal so no problem in the pw. Telekom is much better in handling topics like these. "Da hat etwas nicht geklappt Beim Anmelden ist ein Fehler aufgetreten. Versuche es in ein paar Minuten noch einmal. Hinweis: Mit dem O2 Community Login kannst du dich nicht in die App einloggen"

Hello Jen Gallardo, thank you for your review. Have you ever cleared the cache and storage and then reinstalled the app? If the message continues to appear, please contact customer service or, alternatively, post in the o2 Community so that your data can be reviewed.

No English/other language options; doesn't allow screenshot or allow screen translation. Very limiting if you are not fluent in German for technical topics. Otherwise, the app works OK.

Wir nehmen deine Kritik ernst und prüfen noch mal, an welchen Stellen wir Optimierungsbedarf ableiten können. Alternativ zum Kundenservice kannst du dich bei Fragen auch gern in der o2 Community melden.
