We made some tests with our online demos on few devices with Android 9. The issue was not reproduced. It will be really useful for us, if you share a screenshot of the settings of the report parameter, so we can test further. Can you also check if the issue will be reproduced with our online demos
We have made improvements in the Html5 Viewer since R2 2018, so upgrading may fix the problem. However, since we cannot reproduce locally, we cannot guarantee this. Testing with online demos (they use the latest version) may answer this question.
If possible, please, open a Support ticket
and send us the problematic report to test also with it.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
