I am impressed! it totally makes sense, although I am actually so disappointed by knowing how Android later version was designed.
My Telegram app always gives me notice super fast, while Email is being lazy.. However, I followed the kind advice from Mr/Ms The Penguin and Outlook app is working good so far for me, fortunately, Otherwise, I had no other way but to buy another new phone,, (probably iPhone.. which I don't fancy.. )
Thank you guys so much for your kind help!!
I really hope Google review this restriction,, and I hope Outlook to be able to work for the long term,, I hope I can use Poco F3 as long as possible without experiencing this problem again.
