Common fixes
ReelGrow says it stopped for today
Instagram showed a warning (Try Again Later), so ReelGrow stopped and will come back tomorrow, 20% slower. Use Instagram by hand as normal. A second warning in a week pauses it for 48 hours, a third for 7 days.
It isn't liking anything
Check that you're signed in to Instagram in the same Chrome, that Chrome is open and your computer is awake, and that today is inside the hours and days you set. ReelGrow also waits between batches, so a quiet half hour is normal.
It says Instagram changed
Instagram changed its page in a way ReelGrow didn't expect, so it paused instead of guessing. We fix these quickly; the store update installs by itself.
How do I delete my data?
Everything ReelGrow keeps is on your computer. Settings → Reset deletes it, and so does removing the extension.
