If it is no longer possible to open a PDF report after a measurement, or if you see an error code when you want to open the PDF report, there is most likely a syncronization problem. You can solve this problem by logging out of the app and then logging in again.
If the problem still arises after this, please send us an email to firstname.lastname@example.org with answers to the following questions:
- Which phone/ tablet model do you use (e.g. iPhone 13)?
- What version of iOS/Android does the phone/ tablet run on?
- What version of the app are you using?
