I know nothing about how long you’ve had these devices or what you’ve purchased - if you’re unsure what you’ve purchased you can open a ticket on our help desk quoting your licence pool email address and we can look up these details.
If you purchased these devices recently you should have the 1.8 Xibo Player installed and 1.8 licences for that - you can therefore upgrade to R104 and have the bug resolved as mentioned before. If these are recent purchases and you have 1.7 installed, then you should query this with DSDevices.
If you’ve got 1.7 licences and these are not a recent purchase then there is an upgrade fee to go to 1.8 as per our licence agreement. It may be that we back-port the fix to a 1.7 player release at a later date.
In general you can find the Android EULA here: https://xibo.org.uk/eula-android
Our policies on Android licensing are very clear - see Licencing your Xibo for Android Display
I hope this is useful.
As a side note 1.8 R104 is available for download now.
