Need better testing with current versions of Word Press

Seems multiple people have been reporting Paypal buttons at checkout are no longer available once the Word Press version is above 6.3.2. For most sites, the Word Press version automatically updates. The recommended plugin support forum is being ignored by the developer. An update to the resolution would be beneficial. Testing with up-to-date versions of Word Press needs to occur with ETA notes for developers and users. This is a huge problem for customers, since our customers can’t make payments. Looking for an alternative plugin or as others suggested have to revert back to 6.3.2 in order for the buttons to work again.
