Hey @Paul, sorry to hear that you’re having login issues here. We definitely have seen this on our end, and it looks like Google made some mistakes in their own provided software. We were getting stuck on these bad versions too until we removed some problematic website data.
If you clear all website data related to “googleapis.com” then the issue should disappear. I don’t have an iPad handy at the moment, so the process may be different for you, but I think this should still work:
Open Settings, go to Safari, go to the Advanced settings, and under Website Data, search for “googleapis.com”. You’ll see quite a few sites there. We’re not sure which specific site is the problematic one so just delete them all. On iPhones you have to dismiss the keyboard and press the “Edit” button in the lower right hand corner to be able to delete items here.
I’ll have access to an iPad tomorrow to confirm that these general instructions are valid.
