So I just got a new Chrome cast device and was trying to do the setup through my S20. It kept failing during the connect to wifi portion of the setup. When I used my Galaxy Tab A 10.1 it worked fine. I'm making an assumption that it didn't like the beta on here. I was just curious if anyone else came across this or anything like this. I didn't run error reports on my phone quick enough so not trouble ticket submitted.
Have you been able to successfully connect the device? Please try clearing cache and rebooting the device to see if the problem is resolved. If not, please send us an error report.
