@adriaanrosecottage Beta version v5.2.23 already has the online license check issue resolved, I have used it on 3 live setups and it works fine. Make sure you use latest Android app version v2.0.45 (you can update via Google Play store).
If you want to try this now, this is the way you can.
However please note there is a known issue with latest beta v5.2.23 related to some on screen keyboards not working with touchscreen. This will be resolved in a later beta release or release version v5.2.24. So I do not recommended to install beta v5.2.23 on a production setup unless you always have a keyboard connected.
