Is there something we can investigate on our end, or is this likely due to the user having an outdated device? Any guidance or suggestions would be appreciated.
In general, we do not support too old browser versions, as by defined in the subscription contract. Users should run on evergreen browsers, and have their phones updated on a regularly basis.
However, we try to support a few versions back, as in the case few weeks back where a lot of users had a non-functional app on an old mobile browser version.
In order to consider this one, we need to know the Android version and Browser version. If it is only one user who has the problem, the answer is probably to update the Android or browser on the device.
