Bedrock Edition - Problems with Realm

Hello, I have 1 Realm and I can't download the Realm to my phone .. It says to free up more storage space but I have 20GB free on the phone ... I have already erased all the worlds that I had on my phone and I still can't download Realm to my phone.. I already talked to your support and your employee, you thought it was better to report here. I would like you to help me, please ...
