If you come across a message that Google Sheets can't save your sheets and you need to revert to an earlier version, but even the earlier version can't save, don't bother doing any of these suggested steps. Clearing cookies won't help. Disabling extensions won't help.
Instead, try this (as counterintuitive as it seems): copy and paste your Google Sheets cells into a new Excel workbook. Save the Excel workbook and upload it to Google Drive. Open it with Google Sheets. Save that sheet. Delete your old, non-working sheet.
I recently ran into a weird situation in which the Google Drive desktop app was complaining about there not being enough space to add a folder to my selective sync options. It made no sense. I had at least 100 GB of free space on my drive, and I wanted to additionally sync only another 3 MB in one subfolder.
How could an additional 3 MB take up more than 100 GB of space?
Well, it turns out there's a bug in Google Drive. The first time you do a selective sync, the trash storage isn't taken into account when Google Drive compares it to the free space on your local drive. But in subsequent changes to your selective sync, the trash storage is taken into account, so if you have a lot in your trash, you can't modify your selective sync.
I've reported the bug to Google. In the meantime, if you run into this issue, empty your Google Drive trash (through the web browser, not the app), and then wait about 24 hours. You should then be able to modify the selective sync again.
Can't say this will be the fix every time, but if you use Google Drive to share VideoNot.es with others and the shared notes show up blank, it's likely that you didn't save the notes before sharing.
People can get used to Google Docs autosaving documents as you type (almost in real time) and forget that not all online apps do that. Manually save before sharing your VideoNot.es.
When you try to share a GarageBand project out from the iPad, the immediately apparent options may include only Facebook, SoundCloud, and YouTube (yes, even if you select the More option).
If you want to export your project to Google Drive, you may have to take a few extra steps.
Select your project by either tapping Select or long-pressing on the project icon itself.
Once it's selected, click the share button (looks like an up arrow pointing out of a rectangle).
Select Open in...
Before you can select what to open the project in, you'll have to fill in some details about the song. Fill those in.
Then you should see a lot more applications appear to share it in, including Open in Drive. You may have to do a bit of horizontal scrolling to get it to appear, depending on how many shareable-to apps you have installed.
Once Google Drive opens, you'll then be prompted to upload the song. Select Upload.
