Drafts on my Samsung Android are lagging in Yahoo.

Hello

For about a month now, when I click on one of my Drafts in YahooMail, I can't open them; they lag. I have to open 7 or 8 different drafts for it to finally open, and then I go back to the draft that was lagging before, and then it finally opens, but it can take 5 to 10 minutes and really annoy me.

I want to specify that I have cleared the Yahoo Mail "cache" several times and that hasn't changed anything. I then uninstalled the Yahoo app from my phone, turned it off completely, then restarted it, and I cleaned my System with the Maintenance tab of the device. Then I reinstalled Yahoo Mail, and miraculously the Drafts opened instantly, but that didn't last long because the next day it started again until now. I don't know what else to do; I even removed the SIM card, turned my phone back on, cleaned the memory system, cleared my Chrome browser, what else can I do??

My phone is a Samsung A70, and I have no issues with other apps, and I ran 2 system cleaning scans, and everything is fine.

Thank you for your help.
