Caution Advised. Uninstalling IS app to solve app issues might present with other issues.

This post is to warn users who might be unaware that uninstalling this app to reset an issue is not recommended and to seek advice. I couldn't do lessons yesterday, I closed and reopened, cleared up the cache, emailed IS customer care, nothing worked. So I decided to try uninstall and reinstall the app on one of my two phones, luckily I only tried it on only one of the phones. I have since been able to complete today's lesson on my other phone where the app wasn't uninstalled and that's where I'm writing this post. After reinstalling the app, every previously earned or saved record disappeared. The shards, the streak, user level, awards, everything gone. I couldn't even purchase a Streak Reviver. A Streak Reviver, separate from a Streak Protector, is precisely for this exact scenario but I couldn't since I needed 1250 shards to do that. But on my other phone where I'm writing this, I have 39.3K shards, 544 user level, 200++ days streak, Champion II.

I mean, the same account, same user, two phones should perfectly sync, right? I will send this post as an email to the Support team and see what they advise.

So, this post is as much a suggestion, a warning to other users and SOS for help if anyone knows what I can do to get the app running again as before, and with the streaks, shards and everything else restored.

Thanks for your help.
