Thanks for the report. Did you make your repo public? I cannot access it.

Also, does this behavior reproduce with a regular <input type="text" />?

Thanks, I can access the repo now. It looks like this is a longstanding bug in Android Chrome, not Ionic: https://bugs.chromium.org/p/chromium/issues/detail?id=647704&q=maxlength&can=2

ion-textarea uses a <textarea> element internally so we are relying on the browser to provide the correct maxlength behavior.

Quick Update:

1. we tried testing in several ios devices as well and we observed the same behavior for only IPHONE 11 IOS 14.2.0 Rest of all devices didn't showed up same behavior.
2. Yes, this behavior can be reproduced with a regular

Any leads/workarounds will be highly appreciated.
Thanks
