- Change Spatial Audio to Stereo.
Method 2: Update Your Instagram App

FAQs
Read all these questions to find out how you can fix this common sync issue on your iPhone 17 Pro Max.
Q1. Will iPhone 17 Pro Max Reels BeatSync return after the iOS 26.4 beta update or the Instagram purge?
Ans. iOS 26.4 betas improve audio processing; test post-update.
Q2. Does the LumaFusion or CapCut plugin interfere with Instagram’s native AI beat align on iPhone 17?
Ans. Generally, no! Using CapCut or the LumaFusion plugin doesn’t interfere with Instagram. However, this native AI beat alignment tool is designed to decode the video content that is uploaded on Instagram Reels.
Q3. How long until lost Reels views recover after fixing the iPhone 17 Pro Max beat sync glitch?
Ans. The time can take 7 to 14 days after resolving this beat sync error on your iPhone 17 Pro Max.
Q4. What if TikTok beats sync perfectly, but Instagram Reels AI fails on the same iPhone 17 Pro Max clip?
Ans. The prime reason is that Instagram won’t be able to handle 4K/60fps video compression. Besides this, the audio and video are not fully aligned; that is known as a lip-sync or audio-video desync error.
Q5. Can Instagram’s “Use less mobile data” setting cause Reel beat sync or quality issues on iPhone 17 Pro Max?
Ans. Yes, it can affect how your Reel is processed during upload. If this setting is turned on, Instagram may reduce upload quality or delay media processing, which can make sync issues harder to diagnose. For the best results, turn off Use less mobile data and enable Upload at highest quality before posting your Reel.
Q6. Can old Instagram Reel drafts cause AI Beat Sync problems on iPhone 17 Pro Max?
Ans. In some cases, yes. Old or partially processed drafts can carry over timeline glitches, cached audio data, or failed sync settings from earlier edits. If your Reel keeps failing, create a fresh project, re-import the video, and test the beat sync again instead of reusing an older draft.
