I have this problem, but it's on PCs not on tablets. And like you, we have to clear the cache, and sometimes reset the browser to make it function.
And part of our issue is that we are using Mobilock to lock down the tablets so users can only do what they need to do (basically web and e-mail access only). So when they hit the cache wall it becomes a work stoppage because they cannot make changes to the tablets themselves.
It sounds on the surface at least that we are both suffering from some sort of cache corruption.
Yeah, that would make sense. I almost wish there was a way to disable caching on the tablets.
I like hangouts, but i think its way too complicated for non-techy users. Hangouts really doesn't like texting phone contacts. It almost forces you to convert everyone to Google Contacts. Also if you have Google Voice, it will randomly text some people with your Google Voice number . It took me awhile to figure out that I was texting people from Google Voice instead of my carrier number. I found that in settings it tries to reply with the last number you used.
Overall its better than any texting app I have used, but its a real pain in the ass to configure and nothing is really explained.
Yeah, I guess I can see that. What's weird is how Airdroid and Hangouts works...Airdroid will only show you messages sent and received to/from your carrier's number. But in Hangouts, it aggregates your Google chat, carrier, and Google Voice messsages all into one stream. Kind of annoying tbh...that it doesn't show everything in Airdroid like it does in Hangouts...
